23.0.60; error: Multibyte character in QP encoding region

[Reiner Steib]

Hi,

a recent change (after 2008-03-14) in the Emacs trunk breaks sending
mail with message mode.

To reproduce:

Start "emacs -Q".  In *scratch* eval...

(progn
  (setq debug-on-error t)
  (message-mail "foo" (concat "B"
                              (string (make-char 'latin-iso8859-1 228));; ä
                              "r")))

,----[ *mail to foo* ]
| To: foo
| Subject: Bär
| From: [your name]
| --text follows this line--
| [...]
`----

In the buffer *mail to foo* press `C-u M-x mml-preview RET'

Expected behavior (this is what I get with the version from 2008-03-14
09:20 CET):

,----[ *Raw preview of mail to foo* ]
| To: foo
| Subject: =?utf-8?Q?B=C3=A4r?=
| [...]
| MIME-Version: 1.0
| Content-Type: text/plain; charset=us-ascii
`----

Current behavior (see version info below):
