AFAIK, the translation to unicode etc is done at the client end, using special
browsers you can download from the registrar's site
At the server end, it stays as ascii (though totally gibberish ascii such as
fgry3yerytegsfgr4334.drwy or something). Exim won't have to do anything
(except when, perhaps, domain names grow significantly longer - several
languages are polysyllabic in nature, and have far longer words than english
does)
