As you've probably found out, these are very hard problems.
The build process of my HBase project automatically downloads the official data files from the Unicode web-site and automatically converts them into useful Haskell functions by the miracle of m4 -- including this one: toUpperCase :: Char -> Char; I also have the names for all the characters, because hard-drive space is cheap: getCharacterName :: Char -> String; ...and many other useful normative and informative character properties, such as general category, etc. See http://sourceforge.net/projects/hbase/. Mind you it's in a bit of an odd state right now. As for vowels, I'm pretty sure Unicode has nothing to say on the subject, as different languages may share the same characters but have different ideas as to what is and what isn't a vowel. -- Ashley Yakeley, Seattle WA
