Properly Encoding URL that contain spaces

[vantastic]

Hello

I'm trying to figure out a way to encode url's that contain spaces. Normally I'd manually type %20 as needed, however what I'm doing is part of a form that creates a thread. Allow me to explain.

A user fills out a form with their country, the form is submitted and the variable is pulled for the country to show the flag. The code is something like this:

[img]http://test.com/images/flags/{qo_01}.png[/img]

If the country is more than one word then problems start to happen. The resulting output code is something like this.

[img][url]http://test.com/images/flags/United[/url] States

Notice its all broken because it auto-parses the url and breaks at the first space character. Actually it's a lot worse at the beginning it will include actual HTML for the [img] bbcode, but for demonstrative purposes, this is the part that concerns me.

It should be:

[img]http://test.com/images/flags/United%20States.png[/img]

The variable {qo_01} needs to have any spaces substituted with the %20 characters.

I know how to do this in php, but is there some inline <vb: xx> function that can help? I've thought about BBCode for it too, but haven't tried anything.

Thanks in advance!
