How do I remove emoji code using JavaScript? I thought I had taken care of it using the code below, but I still have characters like 🔴.

function removeInvalidChars() {
    return this.replace(/[\uE000-\uF8FF]/g, '');
}

For me none of the answers completely removed all emojis so I had to do some work myself and this is what i got :

text.replace(/([\u2700-\u27BF]|[\uE000-\uF8FF]|\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDFFF]|[\u2011-\u26FF]|\uD83E[\uDD10-\uDDFF])/g, '');

Also, it should take into account that if one inserting the string later to the database, replacing with empty string could expose security issue. instead replace with the replacement character U+FFFD, see : http://www.unicode.org/reports/tr36/#Deletion_of_Noncharacters

Tried many solutions, but this one was a great success! A note to anyone working with the Twitter API - this worked for me!
This covers a pretty solid range, but I had to make a few edits to cover some omissions. Specifically, I extended the existing character set [\u2694-\u2697] to [\u2580-\u27BF] to include some additional shapes and dingbats, which now matches the common ❤️ character (\u2764\uFE0F). I also extended \uD83E[\uDD10-\uDD5D] to \uD83E[\uDD10-\uDDFF] to catch a handful of emoji such as 🧠, 🦄, 🦊, 🥦, and 🥪.
@CalebMiller, would you care to post your final regex?
Hi @avalanche1, yeah this is what I used, I ended up making additional improvements as well: /[\uE000-\uF8FF]|\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDFFF]|[\u2580-\u27BF]|\uD83E[\uDD10-\uDDFF]/g
Add | before \g, and it'll take care of any whitespaces too. In case anyone need it: /[\uE000-\uF8FF]|\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDFFF]|[\u2580-\u27BF]|\uD83E[\uDD10-\uDDFF]| /g

The range you have selected is the Private Use Area, containing non-standard characters. Carriers used to encode emoji as different, inconsistent values inside this range.

More recently, the emoji have been given standardised 'unified' codepoints. Many of these are outside of the Basic Multilingual Plane, in the block U+1F300–U+1F5FF, including your example 🔴 U+1F534 Large Red Circle.

You could detect these characters with [\U0001F300-\U0001F5FF] in a regex engine that supported non-BMP characters, but JavaScript's RegExp is not such a beast. Unfortunately the JS string model is based on UTF-16 code units, so you'd have to work with the UTF-16 surrogates in a regexp:

return this.replace(/([\uE000-\uF8FF]|\uD83C[\uDF00-\uDFFF]|\uD83D[\uDC00-\uDDFF])/g, '')

However, note that there are other characters in the Basic Multilingual Plane that are used as emoji by phones but which long predate emoji. For example U+2665 is the traditional Heart Suit character ♥, but it may be rendered as an emoji graphic on some devices. It's up to you whether you treat this as emoji and try to remove it. See this list for more examples.

How would you handle emojis with mutliple codepoints such as the warning emoji? That one uses U+26A0 followed by U+FE0F. Your regex would leave the second codepoint untouched

I solved it by using a regex with Unicode property escapes. I got it from this article, it's for Java but still very helpful - Remove Emojis from a Java String.

'Smile😀'.replace(/[^\p{L}\p{N}\p{P}\p{Z}^$\n]/gu, '');

It removes all symbols except:

  • \p{L} - all letters from any language
  • \p{N} - numbers
  • \p{P} - punctuation
  • \p{Z} - whitespace separators
  • ^$\n - add any symbols you want to keep

This one should be more correct and it works, but for me it leaves some trash symbols in the string:

'Smile😀'.replace(/\p{Emoji}/gu, '');

Unfortunately it removes ^ and $. Should be /[^\p{L}\p{N}\p{P}\p{Z}{\^\$}]/gu
Works fine, but disables enter key. /[^\p{L}\p{N}\p{P}\p{Z}\n]/gu - this enables enter
In case of complex emoji. For example: '👨🏿‍🎤'.replace(/\p{Emoji}/gu, '').charCodeAt(0)
I tested /\p{Emoji}/gu and it remove numeric values. "Test123😊" become "Test".
@vozaldi replacing "Emoji_Presentation" instead of "Emoji" appears to remove emojis but not numbers.

I've found many suggestions around but the regex that have solved my problem is:

/(?:[\u2700-\u27bf]|(?:\ud83c[\udde6-\uddff]){2}|[\ud800-\udbff][\udc00-\udfff]|[\u0023-\u0039]\ufe0f?\u20e3|\u3299|\u3297|\u303d|\u3030|\u24c2|\ud83c[\udd70-\udd71]|\ud83c[\udd7e-\udd7f]|\ud83c\udd8e|\ud83c[\udd91-\udd9a]|\ud83c[\udde6-\uddff]|\ud83c[\ude01-\ude02]|\ud83c\ude1a|\ud83c\ude2f|\ud83c[\ude32-\ude3a]|\ud83c[\ude50-\ude51]|\u203c|\u2049|[\u25aa-\u25ab]|\u25b6|\u25c0|[\u25fb-\u25fe]|\u00a9|\u00ae|\u2122|\u2139|\ud83c\udc04|[\u2600-\u26FF]|\u2b05|\u2b06|\u2b07|\u2b1b|\u2b1c|\u2b50|\u2b55|\u231a|\u231b|\u2328|\u23cf|[\u23e9-\u23f3]|[\u23f8-\u23fa]|\ud83c\udccf|\u2934|\u2935|[\u2190-\u21ff])/g

A short example

function removeEmojis (string) {
  var regex = /(?:[\u2700-\u27bf]|(?:\ud83c[\udde6-\uddff]){2}|[\ud800-\udbff][\udc00-\udfff]|[\u0023-\u0039]\ufe0f?\u20e3|\u3299|\u3297|\u303d|\u3030|\u24c2|\ud83c[\udd70-\udd71]|\ud83c[\udd7e-\udd7f]|\ud83c\udd8e|\ud83c[\udd91-\udd9a]|\ud83c[\udde6-\uddff]|\ud83c[\ude01-\ude02]|\ud83c\ude1a|\ud83c\ude2f|\ud83c[\ude32-\ude3a]|\ud83c[\ude50-\ude51]|\u203c|\u2049|[\u25aa-\u25ab]|\u25b6|\u25c0|[\u25fb-\u25fe]|\u00a9|\u00ae|\u2122|\u2139|\ud83c\udc04|[\u2600-\u26FF]|\u2b05|\u2b06|\u2b07|\u2b1b|\u2b1c|\u2b50|\u2b55|\u231a|\u231b|\u2328|\u23cf|[\u23e9-\u23f3]|[\u23f8-\u23fa]|\ud83c\udccf|\u2934|\u2935|[\u2190-\u21ff])/g;
  return string.replace(regex, '');
}

Great answer for me. However a mistake in the regex causes this to also match right brackets ([). Looks like just a mistake from copying and pasting code, but Lucas please fix. Fixed regex here: pastebin.com/0VZZKfWf
I would extend given regex with [\u200d] and [\ufe0f]. They are both special characters, which helps create emoji sequences. If you use just the regex above to remove emojis, your text will contain a lot of these whitespace chars. See evgenyzborovsky.com/2018/04/07/the-ultimate-guide-to-emojis

Just an addition to @hababr answer.

If you need to get rid of complicated emojis, you have to remove also additional things like modifiers and etc:

'👨🏿‍🎤'.replace(/[\p{Emoji}\p{Emoji_Modifier}\p{Emoji_Component}\p{Emoji_Modifier_Base}\p{Emoji_Presentation}]/gu, '')

But note that *#0-9 are technically considered Emoji characters with a text representation by default, per the Unicode Standard.

So to remove emojis without removing those characters:

'👨🏿‍🎤'.replace(/(?![*#0-9]+)[\p{Emoji}\p{Emoji_Modifier}\p{Emoji_Component}\p{Emoji_Modifier_Base}\p{Emoji_Presentation}]/gu, '')

I believe that with the unicode character class escape, available since 2015, can exclude all emojis that belong to only using Extended_Pictographic, while keeping the numbers that would be filtered out by Emoji, as well as single-character emojis like ❤.

After searching and trying lots of unicode regex, I suggest you try this, it can cover all of emojis:

function removeEmoji(str) {
  let strCopy = str;
  const emojiKeycapRegex = /[\u0023-\u0039]\ufe0f?\u20e3/g;
  const emojiRegex = /\p{Extended_Pictographic}/gu;
  const emojiComponentRegex = /\p{Emoji_Component}/gu;
  if (emojiKeycapRegex.test(strCopy)) {
    strCopy = strCopy.replace(emojiKeycapRegex, '');
  }
  if (emojiRegex.test(strCopy)) {
    strCopy = strCopy.replace(emojiRegex, '');
  }
  if (emojiComponentRegex.test(strCopy)) {
    // eslint-disable-next-line no-restricted-syntax
    for (const emoji of (strCopy.match(emojiComponentRegex) || [])) {
      if (/[\d|*|#]/.test(emoji)) {
        continue;
      }
      strCopy = strCopy.replace(emoji, '');
    }
  }

  return strCopy;
}
let a = "1️⃣aa🤹‍♂️b#️⃣🔤✅❎23#!^*bb🤹🏾🤹‍♀️🚴🏻ccc";
console.log(removeEmoji(a))

It seems a bit overcomplicated. Since you're already using Extended_Pictographic and Emoji_Component, you could combine them so that only one replace function runs. Multiple replaces consume more resources - unnecessarily -. See here: stackoverflow.com/a/79511230/15167500

I know this post is a bit old, but I stumbled across this very problem at work and a colleague came up with an interesting idea. Basically instead of stripping emoji character only allow valid characters in. Consulting this ASCII table:

http://www.asciitable.com/

A function such as this could only keep legal characters (the range itself dependent on what you are after)

function (input) {
            var result = '';
            if (input.length == 0)
                return input;
            for (var indexOfInput = 0, lengthOfInput = input.length; indexOfInput < lengthOfInput; indexOfInput++) {
                var charAtSpecificIndex = input[indexOfInput].charCodeAt(0);
                if ((32 <= charAtSpecificIndex) && (charAtSpecificIndex <= 126)) {
                    result += input[indexOfInput];
                }
            }
            return result;
        };

This should preserve all numbers, letters and special characters of the Alphabet for a situation where you wish to preserve the English alphabet + number + special characters. Hope it helps someone :)

Great. Would add new line and carriage return to that though (ASCII 10 and 13)
What if I need to keep locale-specific characters like cyrillic, hebrew, etc

@bobince's solution didn't work for me. Either the Emojis stayed there or they were swapped by a different Emoji.

This solution did the trick for me: 

var ranges = [
  '\ud83c[\udf00-\udfff]', // U+1F300 to U+1F3FF
  '\ud83d[\udc00-\ude4f]', // U+1F400 to U+1F64F
  '\ud83d[\ude80-\udeff]' // U+1F680 to U+1F6FF
];


$('#mybtn').on('click', function() {
  removeInvalidChars();
})

function removeInvalidChars() {
  var str = $('#myinput').val();

  str = str.replace(new RegExp(ranges.join('|'), 'g'), '');
  $("#myinput").val(str);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myinput"/>
<input type="submit" id="mybtn" value="clear"/>

None of the answers here worked for all the unicode characters I tested (specifically characters in the miscellaneous range such as ⛽ or ☯️).

Here is one that worked for me, (heavily) inspired from this SO PHP answer:

function _removeEmojis(str) {
  return str.replace(/([#0-9]\u20E3)|[\xA9\xAE\u203C\u2047-\u2049\u2122\u2139\u3030\u303D\u3297\u3299][\uFE00-\uFEFF]?|[\u2190-\u21FF][\uFE00-\uFEFF]?|[\u2300-\u23FF][\uFE00-\uFEFF]?|[\u2460-\u24FF][\uFE00-\uFEFF]?|[\u25A0-\u25FF][\uFE00-\uFEFF]?|[\u2600-\u27BF][\uFE00-\uFEFF]?|[\u2900-\u297F][\uFE00-\uFEFF]?|[\u2B00-\u2BF0][\uFE00-\uFEFF]?|(?:\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDEFF])[\uFE00-\uFEFF]?/g, '');
}

(My use case is sorting in a data grid where emojis can come first in a string but users want the text ordered by the actual words.)

thank you for this. One thing I noticed it that it wasn't catching all emojis. I found another regex string but it is doing something funky like deleting the character before and adding characters. I can't seem to figure out the difference. Here is a comparison in JSbin between yours and the other: link
Thank you. This saves me a lot of time. Don't forget to add .trim() after the end to remove the empty spaces.

sandre89's answer is good but not perfect. I spent some time on the subject and have a working solution.

var ranges = [
  '[\u00A0-\u269f]',
  '[\u26A0-\u329f]',
  // The following characters could not be minified correctly
  // if specifed with the ES6 syntax \u{1F400}
  '[🀄-🧀]'
  //'[\u{1F004}-\u{1F9C0}]'
];


$('#mybtn').on('click', function() {
  removeInvalidChars();
});

function removeInvalidChars() {
  var str = $('#myinput').val();
  str = str.replace(new RegExp(ranges.join('|'), 'ug'), '');
  $("#myinput").val(str);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myinput" />
<input type="submit" id="mybtn" value="clear" />

Here is my CodePen

There are some points to note, though.

  1. Unicode characters from U+1F000 up need a special notation, so you can use sandre89's way, or opt for the \u{1F000} ES6 notation, which may or may not work with your minificator. I succeeded pasting the emojis directly in the UTF-8 encoded script.

  2. Don't forget the u flag in the regex, or your Javascript engine may throw an error.

Beware that things may not be working due to the file encoding, character set, or minificator. In my case nothing worked until I took the script off an .isml file (Demandware) and pasted it into a .js file.

You may gain some insight by referring to Wikipedia Emoji page and How many bytes does one Unicode character take?, and by tinkering with this Online Unicode converter, as I did.

str.replace(emoji, "");

i add this '\uD83E[\udd00-\uddff]'

these emojis were updated when 2018 june

if u want block emojis after other update then use this

str.replace(/[^0-9a-zA-Zㄱ-힣+×÷=%♤♡☆♧)(*&^/~#@!-:;,?`_|<>{}¥£€$◇■□●○•°※¤《》¡¿₩\[\]\"\' \\]/g ,"");

u can block all emojis and u can only use eng, num, hangle, and some Characters thx :)

There is a modern solution using categories

Modern browsers support Unicode property, which allows you to match emojis based on their belonging in the Emoji Unicode category. For example, you can use Unicode property escapes like \p{Emoji} or \P{Emoji} to match/no match emoji characters. Note that 0123456789#* and other characters are interpreted as emojis using the previous Unicode category. Therefore, a better way to do this is to use the {Extended_Pictographic} Unicode category that denotes all the characters typically understood as emojis instead of the {Emoji} category.

const withEmojis = /\p{Extended_Pictographic}/u

withEmojis.test('😀😀'); 
//true

withEmojis.test('ab');
//false

withEmojis.test('1');
//false

This won't match keycap variation of digits: 1️⃣, 2️⃣, *️⃣, etc. @grabus' answer will, and will convert those to the non-keycap ascii variation, which might be desirable for some.

This is the iteration on @hababr's answer.
His answer removes lots of standard chars like $, +, < and so on.
This version keeps all of them (except for the \ backslash - dunno how to properly escape it).

"hey😁 hau💓 ahoy🏴‍☠️ !@#$%^&*()-_=+±§;:'\|`~/?[]{},.<>".replace(/[^\p{L}\p{N}\p{P}\p{Z}{^$=+±\\'|`\\~<>}]/gu, "")

In detail, this function first uses TextEncoder to convert content into a byte array with utf-8 encoding, then loops through this array, if it finds a byte whose first five bits are 11110 (i.e. 0xF0), it means this is an emoji start, then it replaces this byte and the next three bytes with 0x30 (i.e. number 0). Finally, it uses TextDecoder to convert the modified byte array back to a string, and uses replaceAll method to remove extra 0s.

function removeEmoji (content) {
  let conByte = new TextEncoder("utf-8").encode(content);
  for (let i = 0; i < conByte.length; i++) {
    if ((conByte[i] & 0xF8) == 0xF0) {
      for (let j = 0; j < 4; j++) {
        conByte[i+j]=0x30;
      }
      i += 3;
    }
  }
  content = new TextDecoder("utf-8").decode(conByte);
  return content.replaceAll("0000", "");
}

Please explain your answer. Don't just dump code and expect everyone to understand it.
As it’s currently written, your answer is unclear. Please edit to add additional details that will help others understand how this addresses the question asked. You can find more information on how to write good answers in the help center.
I added a code snippet for your answer. Without an explanation, it was a bit hard to understand the answer. However, this solution doesn't filter out only the base emojis and partially handles the ZWJ sequences (since they are composed of base emojis), but the code doesn't know how to handle the new sequences. For filtering all emojis, it's better to use this answer with Extended_Pictographic.

TLDR: I logically explained the answer from start to finish, and the solution I recommend is at the end of the answer; but here at the beginning of the answer, I also highlight it if that's all you're interested in:

  • \p{Extended_Pictographic} (what excludes emojis)
  • with \p{Emoji_Component} (what excludes color-modifiers - unfortunately it also excludes * and # and number (0-9, \d) chars, but you can preserve them using (?!(\*|#|\d))).
function removeEmojis(str) {
  return str.replace(/(?!(\*|#|\d))[\p{Extended_Pictographic}\p{Emoji_Component}]/gu, '');
}

Or if you want to keep the characters *#0123456789 but remove the emoji versions *️⃣#️⃣0️⃣1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣🔟, you need to specifically filter out these emojis like this:

  • [\u0030-\u0039]\ufe0f?[\u20e3] will exclude 1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣🔟 but not 0123456789
  • [\u002A\u0023]?\ufe0f?[\u20e3] will exclude *️⃣#️⃣ but not *#
function removeEmojis(str) {
  return str.replace(/(?!(\*|#|\d))[\p{Extended_Pictographic}\p{Emoji_Component}]|[\u0030-\u0039]\ufe0f?[\u20e3]|[\u002A\u0023]?\ufe0f?[\u20e3]/gu, '');
}

Or, if filtering out color modifiers is not an issue for you because you only want to filter out simpler emojis, using just Extended_Pictographic might be sufficient:

function removeEmojis(str) {
  return str.replace(/[\p{Extended_Pictographic}]/gu, '');
}

This solution filters out all official emojis, which you can find here:


I saw the {Emoji} and other Unicode character class escapes in some answers to achieve the goal, but no one explains how they work, which have been part of the baseline since July 2015:

The {Emoji}, as mentioned in some of the answers, can indeed be used to filter emojis. However, unfortunately, it also filters out numbers, as pointed out in a comment. So, this is not a complete solution.

However, we do have the option to filter emojis using Unicode character class escapes, in several ways. One approach is to not filter every emoji, meaning we keep characters like 1, 2, 3, ... and ❤, etc. by {Emoji_Presentation}.

function removeEmojis (str) {
  return str.replace(/[\p{Emoji_Presentation}]/gu, '');
}

let text = "Hello 🌍! This is a test with ❤️ and 123. 😃";
let cleanedText = removeEmojis(text);

console.log(cleanedText); // "Hello ! This is a test with ❤️ and 123."

To filter out emojis composed of multiple characters, you can also use: \u200B-\u200D\uFE0F\u20E3

function removeEmojis (str) {
  return str.replace(/[\p{Emoji_Presentation}\u200B-\u200D\uFE0F\u20E3]/gu, '');
}

let text = "Hello 🌍! This is a test with ❤️ and 123. 😃";
let cleanedText = removeEmojis(text);

console.log(cleanedText); // "Hello ! This is a test with ❤ and 123."

Recommended

However, after reviewing the mentioned tables, the most promising one seems to be Extended_Pictographic:

  • These characters are pictographic, or otherwise similar in kind to characters with the Emoji property.
  • The Extended_Pictographic property is used to customize segmentation (as described in [UAX29] and [UAX14]) so that possible future emoji ZWJ sequences will not break grapheme clusters, words, or lines. Unassigned codepoints with Line_Break=ID in some blocks are also assigned the Extended_Pictographic property. Those blocks are intended for future allocation of emoji characters.

function removeEmojis (str) {
  return str.replace(/[\p{Extended_Pictographic}]/gu, '');
}

let text = `
  ABCDEFGHIJKLMNOPQRSTUVWXYZ
  abcdefghijklmnopqrstuvwxyz
  * # 0123456789 /* unfortunately excluded by Emoji_Component */
  *️⃣ #️⃣ 0️⃣1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣🔟 /* excluded by Emoji_Component */

let cleanedText = removeEmojis(text);

Note: It was mentioned earlier, but without further explanation. However, I recently discovered in another question that someone reached a similar conclusion through a similar approach as mine.

To remove some rare combining characters that appear in the ZWJ sequence, it may also be necessary to disable every element of the Emoji_Component; for example, for the emoji 👨🏻‍❤️‍👨🏾, where you can filter out the ‍️‍‍️‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍🏻‍️‍🏾 "color-modifier" characters:

function removeEmojis (str) {
  return str.replace(/[\p{Extended_Pictographic}\p{Emoji_Component}]/gu, '');
}

let text = `
  ABCDEFGHIJKLMNOPQRSTUVWXYZ
  abcdefghijklmnopqrstuvwxyz
  * # 0123456789 /* unfortunately excluded by Emoji_Component */
  *️⃣ #️⃣ 0️⃣1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣🔟 /* exclude by Emoji_Component */
  !@#$%^&*()-_=+[]{};:'",.<>?/
  /* https://www.unicode.org/Public/draft/emoji/emoji-test.txt */
  😀😃😄😁😆😅😂🤣😊😇🙂🙃😉😌😍🥰😘
  /* https://www.unicode.org/Public/draft/emoji/emoji-sequences.txt */
  ⌚..⌛⏩..⏬⏰⏳◽..◾☔..☕♈♓♿
  /* https://www.unicode.org/Public/draft/emoji/emoji-zwj-sequences.txt */
  👨‍❤️‍👨👨‍❤️‍💋‍👨👨‍👦👨‍👦‍👦👨‍👧👨‍👧‍👦👨‍👧‍👧👨‍👨‍👦👨‍👨‍👦‍👦👨‍👨‍👨🏻‍❤️‍👨🏾
`;
let cleanedText = removeEmojis(text);

console.log(cleanedText);

Unfortunately, the Emoji_Component also filters out all the * and the # and number (0-9, \d) characters along with the modifiers in the string, which we want to keep, like this (?!(\*|#|\d)):

function removeEmojis(str) {
  return str.replace(/(?!(\*|#|\d))[\p{Extended_Pictographic}\p{Emoji_Component}]/gu, '');
}

let text = `
  ABCDEFGHIJKLMNOPQRSTUVWXYZ
  abcdefghijklmnopqrstuvwxyz
  * # 0123456789 /* unfortunately excluded by Emoji_Component, but keep by (?!(\*|#|\d) as normal chars */
  *️⃣ #️⃣ 0️⃣1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣🔟 /* exclude by Emoji_Component, but keep by (?!(\*|#|\d) as normal chars */
  !@#$%^&*()-_=+[]{};:'",.<>?/

let cleanedText = removeEmojis(text);

console.log(cleanedText);

If you want to keep the characters *#0123456789 but remove the emoji versions *️⃣#️⃣0️⃣1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣🔟, you need to specifically filter out these emojis like this:

  • [\u0030-\u0039]\ufe0f?[\u20e3] will exclude 1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣🔟 but not 0123456789
  • [\u002A\u0023]?\ufe0f?[\u20e3] will exclude *️⃣#️⃣ but not *#

function removeEmojis(str) {
  return str.replace(/(?!(\*|#|\d))[\p{Extended_Pictographic}\p{Emoji_Component}]|[\u0030-\u0039]\ufe0f?[\u20e3]|[\u002A\u0023]?\ufe0f?[\u20e3]/gu, '');
}

let text = `
  /* Normal chars and some special chars: */
  ABCDEFGHIJKLMNOPQRSTUVWXYZ
  abcdefghijklmnopqrstuvwxyz
  !@#$%^&*()-_=+[]{};:'",.<>?/
  
  /* Include: */
  * # 0123456789
  
  /* Exclude: */
  *️⃣ #️⃣ 0️⃣1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣🔟 (emojis)
  
  /* Other emojis: */

let cleanedText = removeEmojis(text);
