The *format* looks more like latin-1, right. But the payload of a "%s" item is decoded as utf-8.

At the moment, it's true. My remark is that utf-8 tend to be applied to all kind of files; if someone once decide that non-ascii chars are allowed in (some) string constants, they will be stored in utf-8.
