Under what setups can the drive letter be a non-ASCII character?

But according to my experiments, getenv works in the OEM encoding rather 
than the Windows encoding, so you'd need

    homePath = fromMBSz(getenv("HOMEPATH"), 1).dup;

If you want to make sure all Unicode characters are preserved, you're best 
off using the Windows API

    wchar[] wpath;
    wpath.length = GetEnvironmentVariableW("HOMEPATH", null, 0);
    GetEnvironmentVariableW("HOMEPATH", wpath.ptr, wpath.length);
