The script only patches numeric data into the table (field 8), but does not update the digit field (field 7).

As a result, ideographs used for Chinese digits are not recognized as digits and not evaluated by int(), long() and float():

>>> unicode('三', 'utf-8')
u'\u4e09'

>>> int(unicode('三', 'utf-8'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'decimal' codec can't encode character u'\u4e09' in position 0: invalid decimal Unicode string
> <stdin>(1)<module>()

>>> import unicodedata
>>> unicodedata.digit(unicode('三', 'utf-8'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: not a digit

The code point refers to the digit 3.
