Extended Characters in Server Names

Hi all,

I'd like to know whether it is possible in Europe and Asia to create server
names in their own character set (using extended 8-bit or multibyte
characters) or do server names always have to be in US-ASCII characters
only?

Do all operating systems allow the use of extended characters in server
names?  Even if they do, are people actually doing that?  If different
servers on a network have names in different character sets, how does it
work?

I'd appreciate any input on this.

Thanks,
