What Is URL Encoding and Why It Exists
Percent encoding or URL encoding is a technique of converting characters that are considered as special characters into a safe format that can be recognized by the browsers and the servers. URLs can only contain a restricted number of characters. Only letters and numbers and some special characters are permitted, but not spaces and numerous special characters.
The URLs that contain unsafe characters such as spaces, symbols, and letters that are not English are substituted by a percent mark succeeded by a hexadecimal number. For example, a space becomes %20. This renders the URL valid and understandable by any system.
This is automated by the SpellMistake tool and the URL encoder and decoder, in which users would not have to recall the codes or the rules. It transforms a text into coded URLs in real time.
Simple Examples of URL Encoding
To get a closer idea of what encoding is, consider ordinary symbols that people employ in their daily life. A percent sign (20) is substituted, an ampersand sign (26) is substituted and a question mark sign (3F) is substituted. These characters would not be encoded and would thus disorient browsers or even mangle URLs altogether.
Common URL Encoding Table
| Character | Meaning | Encoded Value |
| Space | Blank space | %20 |
| # | Hash | %23 |
| & | Ampersand | %26 |
| / | Slash | %2F |
| ? | Question mark | %3F |
