Well, we may know if it's UTF-8 like that, but we still don't know what it
is otherwise (which is the problem with real).
I haven't bothered to understand the code, but I think mov has some "legacy"
metadata format that actually has to be in latin1, in which case this
code might be completely correct without any such function.
