Public bug reported:

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

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

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.
