Bugzilla cannot deal with my czech name. GNOME Bugzilla does this perfectly (ie. Comment #2 from Pavel Šefránek) and RH Bugzilla cannot do that (ie. Comment #2 From Pavel Å efránek). I think czech language/chars is not so unusual to RH bugzilla should not handle this.
Any news?
Hmm, this had to be a different charset issue. I have updated my profile and re-entered my name in UTF-8 charset and now it works fine for me. Closing this boog.
