Unicode name validation

Question

In ASCII, validating a name is not too complicated: just make sure all characters are in alphabetical order.

But what about in Unicode (utf-8)? How can I make sure that there are no commas or underscores in the given string (outside the ASCII area)?

(perfect in Python)

Answer 1

Just convert bytestring (your utf-8) to unicode objects and check if all characters are alphabetic:

s.isalpha()

This method is language dependent for bytes.

Answer 4

:

import unicodedata
EXCEPTIONS= frozenset(u"'.")
CATEGORIES= frozenset( ('Lu', 'Ll', 'Lt', 'Pd', 'Zs') )
# O'Rourke, Franklin D. Roosevelt

def test_unicode_name(unicode_name):
    return all(
      uchar in EXCEPTIONS
        or unicodedata.category(uchar) in CATEGORIES
      for uchar in unicode_name)

>>> test_unicode_name(u"Michael O'Rourke")
True
>>> test_unicode_name(u"Χρήστος Γεωργίου")
True
>>> test_unicode_name(u"Jean-Luc Géraud")
True
