Examples

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"
    }
