One of the standard Windows Excel locales is sa_IN, with hex code 0x044F. This raises in exception when passed to Locale.parse():

>>> Locale.parse('sa_IN')
Traceback (most recent call last):

  File "C:\Users\Joe Cool\AppData\Local\Programs\Python\Python37-32\lib\site-packages\babel\core.py", line 331, in parse
    raise UnknownLocaleError(input_id)
babel.core.UnknownLocaleError: unknown locale 'sa_IN'
