	I also have Tbird, and for content I can adapt it but usually
have it set to ignore non-UTF-8 these days, as occasionally, 
someone has an old mailer that sends out 8-bit encoding and Tbird would
seamlessly adapt and send the email back out in the same format.  

	I didn't want to pass on bad encodings when I replied to such
items to a list, so I changed that default.

	However, what Tbird doesn't handle well is local encodings
used in the 'To' or subject lines since there is no encoding line
for those.  In a text archive it can convert and display both in 
UTF-8 format, but even if I set Tbird to respond in the same encoding,
it won't fix the encodings in the header as the content-type: text/plain
doesn't apply to the headers.

	So while archives and the email text can be fixed, the text in
the headers often can't.  The only thing to do is bring it to their attention
and hope they have the technical skills to set their mailer to use
UTF-8.
