bug#4938: 23.1.50; Bad signature with "plain PGP" emails and non-ASCII

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the [email protected] mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

When signing an email with non-ASCII characters in Gnus with "C-c RET s
o" and sending it to myself, I always get a "bad signature" warning in
Gnus.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/local/share/emacs/23.1.50/etc/DEBUG.
