Bug#879204: MIME::Words::encode_mimewords: splits in the middle of a multibyte character, invalid MIME

[Thorsten Glaser]

Package: libmime-tools-perl
Version: 5.503-1
Severity: normal

tglase at helpdesk:~$ perl -MEncode -MMIME::Words -e 'print MIME::Words::encode_mimewords(Encode::encode("UTF-8", "Re: Bildungsurlaub für CCC-Fahrt? [THD#1424195]"), Charset => "UTF-8", Field => "Subject") . "\n";'
Re:=?UTF-8?Q?=20Bildungsurlaub=20f=C3?= =?UTF-8?Q?=83=C2=BCr=20CCC?=-Fahrt?=?UTF-8?Q?=20?=[THD#1424195]

Expected output is something along the lines of:

tglase at tglase:~ $ php
<?php
mb_internal_encoding('UTF-8');
echo mb_encode_mimeheader('Subject: Re: Bildungsurlaub für CCC-Fahrt? [THD#1424195]', 'UTF-8', 'Q', "\015\012") . "\n";
Subject: Re: Bildungsurlaub =?UTF-8?Q?f=C3=BCr=20CCC-Fahrt=3F=20=5BTHD=23?=
 =?UTF-8?Q?=31=34=32=34=31=39=35=5D?=
