In Python 2.x, the re module is really sre, not pcre. I recommend not
to use UTF-8 strings, but convert them to Unicode objects, and pass
those into your regular expressions. Please read the re module
documentation for details; take particular notice of the UNICODE flag,
which determines whether character properties will or will not come
from the Unicode character database.
