22296	Better internationalization support for tags	exz		"When playing around with tags I've found a couple of things that doesn't work as expected when dealing with names that have non-english characters. 

The two problems I've found are that single non a-z chars doesn't seem to work at all, and when two tags are the same except for one character which is non a-z, they seem to collide. One example of this is that you're unable to use the tags ""for"" and ""för"" together. 

I'm not sure if this is something that WordPress is supposed to support but I've got a use case for it and would like to raise the question. 

Here's some tests which shows the problem: https://gist.github.com/3964335

Oddly enough you seem to be able to add the single non a-z tags from the dedicated tags page, but you're still unable to use them in any post. "	enhancement	new	normal	Awaiting Review	Taxonomy	3.4.2	minor
