These two regexes are not the same.

>>> re.compile('([-_.a-zA-Z0-9]+)').match('ä')
>>> re.compile(r'([-\w.]+)').match('ä')
<re.Match object; span=(0, 1), match='ä'>

As Ammar said checking that two regexes always matches the same is very difficult problem. It is the problem of determining if two programs are the same.
