Comment:

 [Windows-only]

 http://bugs.python.org/issue2128 suggests that on Python 2.6.x for
 Windows, any non-ASCII characters will have been irretrievably mangled to
 question-marks in {{{sys.argv}}}. Unfortunately
 {{{win32api.GetCommandLine}}} seems to call {{{GetCommandLineA}}}, not
 {{{GetCommandLineW}}}. The bzr project solved this problem by using
 {{{ctypes}}} to call {{{GetCommandLineW}}}:
 https://bugs.launchpad.net/bzr/+bug/375934 . (bzr is GPL'd, so we can use
 that code.)

 Note that this would require passing the correct unicode argv into
 {{{twisted.python.usage.Options.parseOptions}}} from
 source:src/allmydata/scripts/runner.py , i.e. change
 source:windows/tahoe.py to do
 {{{
 argv = get_cmdline_unicode()  # from bzr patch
 rc = runner(argv[1:], install_node_control=False)
 sys.exit(rc)
 }}}

 (assuming that {{{twisted.python.usage.Options}}} handles Unicode
 correctly, which I haven't tested).
