Coding systems again

[B. T. Raven]

I thought I understood coding systems enough to copy-paste between Emacs 
and Windows apps but I am no longer able to revert (re-code?) text from 
a buffer saved as utf-8 to latin-1. If I have the following in a buffer, 
how can I send it in Mozilla Thunderbird as latin-1?

Theodosiô postea imperante rês aliquâtenus in meliôrem statum adductae sunt.

Circumflex diacritics are part of latin-1 if I'm not mistaken but I 
always get a warning that message contains characters not found in the 
Encoding.
Any help?

Thanks,

Ed

What Emacs version are you using?  Emacs 22.x ought to use UTF-16
(a.k.a. Unicode) encoding when passing text through the Windows
clipboard, so any native Windows application should be happy with the
result.

Can you try pasting the same text into Notepad?  If that works, then
the problem is likely ion Mozilla, not in Emacs.

A very helpful function is in ps-print or ps-spool: it tells you  
which characters can't be printed because they're outside ISO Latin-1  
(at least some version 22.x), which has upper and lower case {aeiou}  
with (and without) circumflex.

You could also use C-u C-x = to see what actually was pasted. Can  
recode give some hints?

A common mistake that people make when trying to design something  
completely foolproof is to underestimate the ingenuity of complete  
fools.

Thanks, Eli and Peter. Part of the problem was a single character Y with 
circumflex (Unicode but not Latin-1). I am using Emacs version 22 but 
copy paste from Emacs to Thunderbird doesn't covert circumflexed vowels 
in Emacs internal representation to Latin-1 in Thunderbird. I got around 
the problem with:
C-x ret c
Latin-1
C-x C-w
and then closing buffer and reloading file. It may be something 
different with Thunderbird. I recently turned on Autodect > Universal 
under View > Character Encoding but I didn't understand what was going 
on. Maybe all I have to to is reboot.
