Python regex uppercase unicode word

Question

I need to find abbreviations text in many languages. Current regex is:

import regex as re
pattern = re.compile('(?:[\w]\.)+', re.UNICODE | re.MULTILINE | re.DOTALL | re.VERSION1)
pattern.findall("U.S.A. u.s.a.")

I don't need u.s.a in the result, i need only uppercase text. [A-Z] won't work in any language except english.

Answer 1

You need to use a Unicode character property in order to match them. re does not support character properties, but regex does.

>>> regex.findall(ur'\p{Lu}', u'ÜìÑ')
[u'\xdc', u'\xd1']
