Issue 2: Invalid IDNs: What do browsers answer?

Some scripts have a restricted syntaxe when used in IDNs. For example, you can't mixe Latin characters (LTR in fact) and some scripts (RTL in fact) in the same label, or have a number at the beginning/end of RTL labels.

- Safari2.0: No reaction on click !?
- Firefox2.0: "Server not found. Firefox can't find the server at المغxرب.museum."
- Camino1.0 (better?): "Address Not Found .museum could not be found. Please check the name and try again."
- Mozilla1.5 (better?): Follow the link normally. It's the .museum registry which display the the address is not in use. ( is not in use)
- Opera9.0 :-): The right message error (shame on the ohers): Invalid URL. "Contains invalid or misplaced characters."
