Then my newsreader would convert the text from windows-1252 to UTF-8
(which is my locale environment) before calling emacs and all would
work fine. The problem is that the encoding is not declared, so the
newsreader does not know that it is windows-1252 and not koi8-r or
EBCDIC or latin-2 or

Fine, how can this be done?
