[Haskell-cafe] Valid Haskell characters

Hi, In Haskell reference, I see the following definitions: uniWhite -> any Unicode character defined as whitespace; uniSmall -> any Unicode lowercase letter; uniLarge -> any uppercase or titlecase Unicode letter; uniSymbol -> any Unicode symbol or punctuation. Where do I get lists for those characters? My first attempt was to check: http://unicode.org/Public/UNIDATA/UnicodeData.txt and consider large anything marked as CAPITAL and small anything marked as SMALL. I didn't know what to guess about the symbols. Am I using the right reference? How can I recognize (or get a list of) valid uppercase and lowercase unicode letters, as well as symbols and punctuation? Thanks for your help, Maurício
