I'm not really sure what you're asking. Haskell's uniSymbol includes all
Unicode characters (should that be codepoints? I'm not a Unicode expert)
in the punctuation category; I'm not sure what the best reference is,
but e.g. table 12 in
    http://www.unicode.org/reports/tr44/tr44-8.html#Property_Values
lists a number of Px categories, and a meta-category P "Punctuation".


Thanks
