about building urls.

If I have a parameter to be passed on the url that includes spaces what method do I use to convert the spaces (or other special characters) to %20?
What about international characters sets… What if the parameter is a name in a different language like Chinese simplified?

Have a look at http://documentation.xojo.com/index.php/EncodeURLComponent . AFAIK it’s ascii for URLs. There is a special encoding called Punycode (see Punycode - Wikipedia) for handling this.
