Summary

Function: string llEscapeURL( string url );

Returns a string that is the escaped/encoded version of url, replacing spaces with %20 etc. The function will escape any character not in {a-z, A-Z, 0-9} to %xx where "xx" is the hexadecimal value of the character in UTF-8 byte form.

• string url

To clarify, numbers and ASCII7 alphabetical characters are NOT escaped. If a character requires more then one byte in UTF-8 byte form then it returns multiple %xx sequences chained together.

This function is similar to functions (e.g. rawurlencode, encodeURIComponent) found in many other languages: 
PHP
rawurlencode
ECMAScript
encodeURIComponent

Caveats

  • The function is not appropriate for escaping a URL all at once, because the ':' after the protocol, and all of the '/' characters delimiting the various parts, will be escaped. Instead, build the URL in parts; escaping parts of the path and query string arguments as needed.

Examples

<lsl> // Provides a clickable link to the LSL Portal by escaping the space in the title // "LSL Portal" here becomes "LSL%20Portal"

string title = "LSL Portal";

default {

   state_entry()
   {
       llOwnerSay("http://wiki.secondlife.com/wiki/" + llEscapeURL(title));
   }

}
