Topics are not recognized if subject contains special characters

[yan]

I defined some topics that are generally recognized correctly from the subject line. But if the subject contains special characters like German "Umlaute" (äöü), Mailman doesn't recognize keywords as topics.

It seems to me that this has to do with the encoding. When the subject contains a special character, its source looks like this ("Mexiko" is my keyword):

Subject: [abo] =?utf-8?q?TEST=3A_Subject_with_special_characters_like_?=
 =?utf-8?b?w6TDvMO2IHwgTWV4aWtv?=

Without special characters, it looks like this, though:

Subject: [abo] TEST: Subject without special characters | Mexiko

In other cases, the source of the subject line did still contain the keyword, but it wasn't recognized.

I'm using version 2.1.12 patched.
