If only it was that simple....
The DNS protocol is 8-bit clean. So in principle it could be used to
look up names in any character set. [For some definition of character
set.] However other protocols define a restricted set of ASCII
characters for things like hostnames and email addresses. If some
applications get presented with non-ASCII characters, bad things could
happen. The applications could crash or behave unpredictably. So if
the DNS returns non-ASCII data in those circumstances things like web
browsing and email could stop working. The IETF has a group working on
internationalised DNS. The general idea is some character encoding
scheme is used to map names expressed in "character sets" in any
language -- Japanese, Russian, Arabic, Chinese, etc -- into ASCII
strings that won't blow up the world's web browsers and mail
software. Progress in this standardisation activity is slow. It's a
very hard problem.
