Building a valid URL By the same token, any code that generates or accepts UTF-8 input might treat URLs with UTF-8 characters as “valid”, but would also need to translate those characters before sending them out to a web server. This process is called URL-encoding or percent-encoding.
What Is percent encoding used for?
Percent-encoding is a mechanism to encode 8-bit characters that have specific meaning in the context of URLs. It is sometimes called URL encoding. The encoding consists of substitution: A ‘%’ followed by the hexadecimal representation of the ASCII value of the replace character.

After testing Internet Explorer, Mozilla Firefox and Google Chrome, only IE doesn’t encode @ from the reserved character to percent encoding. As for unsafe characters, Firefox ignores 11 characters out of 14, Chrome ignores 3 out of 14 and IE encodes all unsafe characters to percent encoding.

How to decode percent with numbers in URLs?
