Problems with the encoding of the list pages

Hi,
since I've updated my mailman instances to 2.1.27 I have problems with the encoding of my list pages. Many of my users are using German Umlauts (Ö, Ä, Ü, ö, ä, ü, ß) in their listconfiguration, e.g. for the list description or the list info texts. Those special characters are broken now, while the other special German characters, that are comming from the template files of the page, are OK.
It seems that the list templates are encoded in ISO-8859-1 and the content, which is unique for every list, is stored an displayed as UTF-8.
I don't know if something went wrong via the update process or what else caused the issue, but with earlier mailman versions I did no have those problems and some of my installations are quite old.
Do you have any idea what I can do to solve this issue? The best IMHO would be to convert the whole setup to UTF-8, but as long as the template files are stored as ISO-8859-1 or do not have any charset stored in the html header of the page, this is difficult.
I have also tried to convert the list settings for every list from UTF-8 back to ISO-8859-1 with the config_list command and iconv. Maybe I could solve the issue this way... What do you think?
Has anything changed in mailman 2.1.27 that caused this encoding issue and do others have those problems also?
cheers and thanks for any help,
Schoepp

I need more information to help with this. What version did you upgrade from? Is this Mailman installed from source or a package? If a package, which, and if Debian/Ubuntu, see the entire thread at <https://bugs.launchpad.net/mailman/+bug/1462755> including all the posts linked from <https://bugs.launchpad.net/mailman/+bug/1462755/comments/6>.
