Strange symbols in decrypted message

[Marius Hofert]

Hi,

I encrypted + signed a message with C-c C-m C-e (GnuPG, PGP/MIME) and send it to
the test server at adele@gnupp.de (after having sent an email with my public key
as attachment to adele@gnupp.de). It came back decrypted (so public key
encryption works), but some characters in the original message were not
displayed correctly. 

I simply used "foo bar" as message text (without quotes), and the message
contained my signature, starting with the separator "--". The decrypted message
sent back to me contained "foo bar=20" instead of "foo bar" and "=2D-=20"
instead of "--". I check the charset, it said us-ascii, so a subset of
utf-8. 

What went wrong? 

Cheers,

Marius
