Bugzilla seems to change the 8-bit special characters to 7-bit. E.g. 'a'
with two dots --> d.
See bug #12250 for an example.
Why not make bugzilla UTF-8 compliant ?
Bugzilla is not 8bit clean. The problem is really, how does bugzilla know
what encoding you're using to submit a report with? And how does it know
what encoding it should use to display the report to another user?
Both are probably solveable, but I don't think it would be an easy task
per se. (or someone would have likely done it by now.) ;o)
If bugzilla did use UTF-8, then how would someone using ISO8859-x to
file a bug report end up with their bug being treated? Garbled as
UTF-8? Not sure, but this sort of thing is more of a major bugzilla
feature request that is probably best to as a request to bugzilla.org

Discussion in bug 80349 seems to indicate that this is fixed now.
