    We have a Windows application (TCL script really) that wants to find the
    IP address of the PC it runs on; it effectively does

      cmd /c "ipconfig > ip.txt"

    then reads the file. This works fine everywhere, except... I have a user
    with WinXP set to Chinese language. For this user, the file stops after
    "Ethernet adapter" (contains just 53 characters). Doing ipconfig without
    redirection in a CommandPrompt window works fine and says the equivalent
    of "Local Area Connection" in Chinese.

    Seems to me that file I/O redirection, angle-brackets or pipe symbols,
    stop at the first non-English character. Is this a known bug or feature?
    If so, does anyone know a workaround? Otherwise, does this have security
    implications?

    Cheers,
