Encoding troubles with Java

Question

How can I make String Стек look like %D0%A1%D1%82%D0%B5%D0%BA? Which encoding is it? How can I do it with Java? I thought it's UTF-8:

 String myString = "Стек";
 byte text[] = myString.getBytes();
 String value = new String(text, "UTF-8");
 System.out.println(value);

But no, I've got Стек in output.

Looks like URL encoding to me. Note that UTF-8 is a text->binary conversion. You're looking for a text->text conversion. — Jon Skeet

It's not UTF-8, it's URL-like encoding, and you can get it using the URLEncoder class:

String encoded = URLEncoder.encode("Стек");
System.out.println(encoded);

Result:

%D0%A1%D1%82%D0%B5%D0%BA

The text that you've shown is Percent encoded or URL encoded.

You can use URLEncoder for converting it to the desired format:

String value = URLEncoder.encode("Стек", "ISO-8859-1");

You can use the URLEncoder class to convert a String to percent encoding:

import java.net.URLEncoder;

System.out.println(URLEncoder.encode("Стек", "utf-8"));

You'll also need to catch UnsupportedEncodingException.
