Hmm... this only works if the Info file is encoded in UTF-8.
I guess in the case of Info, 99% of the files are just ASCII and there's
a chance that the vast majority of the rest is (or will be) UTF-8,
so maybe this hack works well in practice.

But I think we should define an `Info-bytepos-to-charpos' function for that.
It can be defined as an alias for byte-to-position, but at least it
concentrates this utf-8 assumption at a single place where we can place
a clear comment.
