The tests for re include these regexes:

    a.b(?s)
    a.*(?s)b

I understand what Georg said previously about some people preferring to put them at the end, but I personally wouldn't do that because some regex implementations support scoped inline flags, although others, like re, don't.

I think that second regex is a bit perverse, though! :-)

On the other matter, I could make the Unicode script and block available through a couple of functions if you need them, eg:

    # Using Python 3 here
    >>> regex.script("A")
    'Latin'
    >>> regex.block("A")
    'BasicLatin'
