Hi Christian,
you are right, this has not been identified in the ZIM File Format article, even though we have discussed this at our very first Developers Meeting back in 2009:
http://openzim.org/Developer_Meetings/2009-1#Minutes
Everything should be in UTF-8.
I have added a section "Encodings" to the Zim File Format article right now to fix this in our documentation:

Thanks for asking!
