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-zA-Z0-9] to %xx where xx is the hexadecimal value of the character in UTF-8 byte form. This function is similar to the URLEncode()function found in many other languages.

• 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.

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.

string title = "LSL Portal";

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