I see a problem with charsets (see below). The code will if I read it 
correctly only work when the BE uses UTF8.

No, I suggested storing the puny code in the domain table instead of doing 
the conversion again and again. Another reason is that IDNA works on UTF8, 
so any de-/encoding must take care of the current charset.

My idea:

For table sys_domains we add a hook implementaion that translates any user 
input into an IDNA domain (punycoo with ACE prefix). The hook will convert 
the current charset to UTF8 before applying the punyocde transformation if 
necessary. To make the table still accessible I would add a read-only field 
that shows the domain in UTF8.

PS: Could you repost the patch without the IDNA lib? The diff is much too 
large to find out what you have changed.
