Caveats
- The hexadecimal encoded representation of UTF-8 byte encoding is the only supported means of access to non ASCII7 characters (Unicode characters).
- Decoding of Unicode as %u#### is not supported.
- The + character is not decoded as a space.
Examples
<lsl> string str = "http://wiki.secondlife.com/wiki/LSL Portal";
default {
state_entry()
{
llOwnerSay("Plain string:\n\t" + str);
// output: "http://wiki.secondlife.com/wiki/LSL Portal"
llOwnerSay("Escaped string:\n\t" + llEscapeURL(str));
// output: "http%3A%2F%2Fwiki%2Esecondlife%2Ecom%2Fwiki%2FLSL%20Portal"
llOwnerSay("Escaped string unescaped again:\n\t" + llUnescapeURL( llEscapeURL(str) ));
// output: "http://wiki.secondlife.com/wiki/LSL Portal"
// because escaping and unescaping are exact opposite
// and unescaping an escaped string returns the original
// For readability's sake it would make more sense to do:
llOwnerSay("For readability's sake:\n\t" + "http://wiki.secondlife.com/wiki/" + llEscapeURL("LSL Portal"));
// output: "http://wiki.secondlife.com/wiki/LSL%20Portal"
}
