It is not the user data that is munged by *Windows*, but by *Git for
Windows*. The user data on Windows is encoded in UTF-16 (or some slight
variant thereof). Git *cannot* handle UTF-16. Git's test suite *cannot*
handle UTF-16. So we convert. That's all there is to it.


P.S.: Of course it is not *all* there is to it. There is also a current
code page which depends on the current user's current locale. We can
definitely not rely on that, as Git has no idea about this and would quite
positively produce incorrect output because of it. So we really just use
the `*W()` functions of the Win32 API (i.e. the ones accepting wide
Unicode characters and strings, i.e. UTF-16). I don't think we can do
better than that.
