Hi! I strongly support the use of UTF-8 in keys. We shouldn't restrict that just to make it easier for programmers.
But, being a programmer myself, I know programmers are lazy. And while I don't see problems with general Unicode characters, I do see problems with special characters such as "=" (because we generally use it as delimiter between key and value) and "<", ">", and quotes etc. They are special in many databases, XML, HTML etc. and allowing them always sooner or later breaks programs and, worse, creates security holes (SQL injection, x-site-scripting, ...). Sure, they can be avoided if you take care, but who does? (We already had a security problem because of a similar thing a few weeks ago.) So if anybody would propose to not allow some of these characters in tag keys (or, for that matter, user names), I'd be in favour. On the other hand, we must allow these in tag values anyway, so maybe its not worth it.
