Python3.0.1 is not available when system locale is zh_TW.eucTW

Expected result: python3.0 interpreter should works fine.
Actual result: python3.0 interpreter can not execute any statement or
ran python program.

Steps to reproduce this bug:
1. Login HP-UX with a locale 'zh_TW.eucTW'.
2. Install ActivePython-3.0.1.1-hpux11.00-parisc.tar.gz on a HP-UX 11.11
machine.
3. Start the python3.0 interpreter.
4. Try some python statements like following, there was not any reaction:
    import locale
    locale.getlocale()
    help()
    exit()
5. Try to run a python program like following, but it was not run.
    python3.0 foo.py

Notes:
1. This error does not occur when the system locale is 'zh_TW.big5'.
2. This error was also found on linux build.
