Actually, I think it’s misreporting the message content as UTF-16, while it is in fact encoded as UTF-8. So the error appears to be on the sender side.

Apparently, Apple Mail.app is rather strict about following the reported encoding, while Gmail for example does some attempt to guess. That would explain the less terrible results with Gmail.

I can base64 decode the message just fine on the command line, which runs in a terminal emulator (Apple’s Terminal.app) that does handle UTF-8, but not UTF-16 by default.
