How to use URL encode in HTML
If a URL contains characters outside the ASCII set, the URL has to be converted. URL encoding converts non-ASCII characters into a format that can be transmitted over the Internet. URL encoding replaces non-ASCII characters with a "%" followed by hexadecimal digits. URLs cannot contain spaces.

What is URL encoding with example
All characters to be URL-encoded are encoded using a '%' character and a two-character hex value corresponding to their UTF-8 character. For example, 上海+中國 in UTF-8 would be URL-encoded as %E4%B8%8A%E6%B5%B7%2B%E4%B8%AD%E5%9C%8B .

"%40" in a URL means "@". If you want a "%" to mean "%", you need to URL encode it to "%25". URL encoding is just a transport encoding. If you feed in "@", its transport encoded version is "%40", but the recipient will get "@" again.

Is UTF 8 human readable
The first 128 characters in the Unicode library match those in the ASCII library, and UTF-8 translates these 128 Unicode characters into the same binary strings as ASCII. As a result, UTF-8 can take a text file formatted by ASCII and convert it to human-readable text without issue.
Does URL encoding prevent XSS
Encoding is probably the most important line of XSS defense, but it is not sufficient to prevent XSS vulnerabilities in every context. You should also validate input as strictly as possible at the point when it is first received from a user.
What is %2f in HTML

Why is UTF-16 better than UTF-8
UTF-16 is better where ASCII is not predominant, since it uses 2 bytes per character, primarily. UTF-8 will start to use 3 or more bytes for the higher order characters where UTF-16 remains at just 2 bytes for most characters.
Should I use UTF-8 or UTF-16
UTF-16 must encode these same characters in either two or four bytes. This means that an English text file encoded with UTF-16 would be at least double the size of the same file encoded with UTF-8. UTF-16 is only more efficient than UTF-8 on some non-English websites.
How does HTML encoding protect against XSS attacks
Output encoding prevents these attacks by converting the special characters that can trigger XSS, such as <, >, ", ', and &, into harmless HTML entities, such as <, >, ", ', and &. This way, the browser will treat the data as plain text and not as code.
Does Chrome protect against XSS
The HTTP X-XSS-Protection response header is a feature of Internet Explorer, Chrome and Safari that stops pages from loading when they detect reflected cross-site scripting (XSS) attacks.
