Same here :-) ... so there's something weird in my (emacs?)
environment...

Same here. As well as with Latin-1.

On the contrary, UTF-8 sets it fine ;-) as well as if M-x
reset-language-environment, as expected ;)

Strange : that doesn't suffice here... but there may be other
combinations of settings that differ from yours.

Anyway, we seem to have a workaround here, if I just reset the language environment...
But I wonder what other side-effects there may be.

Still, just for comparison, Gnus managed well... but maybe because it
doesn't work with UTF-8 ;-)

Thanks for your help.
