[wp-testers] Swedish letters and domain names

This brings up a very good topic for the future: support for UTF-8 and 
Unicode characters in regex with PHP.

I have experience running dedicated CentOS 5.2 servers and shared 
(Hostgator, GoDaddy, etc) servers. None of these platforms, which is 
representative of a non-trivial number of server configurations out 
there, have support for Unicode properties in PCRE. This means that none 
of these platforms can support UTF-8 or other Unicode characters in 
regular expressions by default. For full details on the matter, see my 
blog post on the topic: http://tinyurl.com/dks2te

As far as the topic goes, does anyone have any information on whether or 
not the lack of Unicode support in regex would cause problems?
