URL encoding

URL (Universal Resource Locator) encoding is the method of using ASCII hexadecimal characters to display specific characters in a URL. It is used for several reasons. On some operating systems, certain characters are unsafe or not available, and others are reserved by the HTML or URL specification. URL encoding is used to insure compatibility and functionality with most Internet browsers. As a general rule, use the hexadecimal encoding method shown below when these characters appear in your URLs.

The following types of characters do not require encoding in a URL:

Alphanumeric characters

0-9,a-z,A-Z

 

 

 

 

Special characters

$ _

-

. + ! * ( ) ,

 

 

 

 

Reserved characters

; /

?

: @ = &

NOTE: When used for their reserved purposes, these characters do not require encoding within a URL.
