Special characters in URLs

HTML pages can contain ASCII special characters. The web content contains HTML codes that represent the special characters or symbols.

The HTML codes for special characters start with "&#" and end with ";".

The HTML codes use the following format:

&#<numeric_id>;

where

<numeric_id>: A number or hex representation for the character. The maximum value of the number representation is 255 (Hex: 0xFF).

For example, the percent sign (%) has a numerical code of % and a hex code of %.
