RegEx Validation Check

Question

I am new to Regular Expressions, can't wrap my mind around this one, can anyone please help me out here, what is it doing:

^[A-Za-z0-9~!@#$%^&amp; *()_<>+`\-={}\[\]:;'&quot;,./?|\\\s']{0,8000}$

what possibilities does this left out?

leaves out a lot, what would you like to accomplish with your regex? what do you want to allow and disallow ? — CSᵠ

@CSᵠ can you be more specific like what? One possibility as Cas mentioned is HTML characters, as I didn't write this but happen to find in our code base written by someone else in the past, therefore, I need to clear my concept before new implementation. — Ali

you can't add "html entities" in a regex character class as it would interpret it character by character (eg. /["]/ would match theese characters only: o, q, t, u, & and ; !) — CSᵠ

The site only works for Python, javascript ? seems no c# support ? — now he who must not be named.

I don't know as I didn't write it

@Ali on the site in my answer is the explanation of what it doesn't capture.

@Ali regex101.com/r/rZ5bQ0 here with (i think) pretty much all characters (Alt-combinations left out)

A bit late, but here's some more from my keyboard only (no alt+xxx): regex101.com/r/sP3nX9

@Enissay yeah, thats what i warned Ali for... there are a lot of inputs to forget about very easily.
