The function which generate the 'nicename's is broken for unicode

[Tomer]

I'm about to run a non latin-1 site. While each post is linked with the post nicename, there is no nicename for non latin-1 posts, which gets null strings instead of nicename.

If the system do not like my nicename - it should ask for a manual nicename editing, not to make it null string!

Yes, we should check for null strings and either prompt the user to provide a post slug that satisfies the character restrictions of RFC 2396 or autogenerate a post slug of the form "post #", for example, which the user can edit later.

Has this been resolved yet?

We use the ID if sanitize_title returns an empty string. I was keeping the sanitize bugs open until we decided if we are going to expose category and author slugs in the admin UI. Are we, should we?
