In order to flag use of mixed scripts in numerals, the code does not require access to any additional unicode data. Since Unicode 6.0.0, programmers can rely on the following stability promise: """ Characters with the property value Numeric_Type=de (Decimal) only occur in contiguous ranges of 10 characters, with ascending numeric values from 0 to 9 (Numeric_Value=0..9). """ -- http://www.unicode.org/policies/stability_policy.html Therefore, the validation code can simply check that for all digits in the number, ord(d) - unicodedata.numeric(d) is the same. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10581> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
