Thanks for doing some research. Zenmap already uses that solution. See
zenmapCore/BasePaths.py:

    fs_enc = sys.getfilesystemencoding()
    if fs_enc is None:
        fs_enc = "UTF-8"
    raw_home = os.path.expanduser("~")
    home = raw_home.decode(fs_enc)

But it doesn't work for my user with the Japanese name, unless the
system locale is set to Japanese. My guess is that with the locale set
to English, the filesystem encoding can't even represent the Japanese
characters. They are replaced with '?'. The error Zenmap gives you in
this case is one that comes from Windows, essentially saying that '?' is
not legal in a file name.
