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 

	 toUpperCase :: Char -> Char;

I also have the names for all the characters, because hard-drive space is 

  getCharacterName :: Char -> String;

...and many other useful normative and informative character properties, 
such as general category, etc.

See <>. 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.
