Might it make sense for Data.Char to re-export GeneralCategory,
generalCategory and toTitle?

The new predicates could be moved to Data.Char.

isDigit returns True for all decimal numbers (Nd), not just the
documented [0-9].  Won't this break readDec and readHex?  If there
is a predicate selecting Nd, you also need a function giving the
value of a digit, as well as a predicate for ASCII digits.

isPrint returns True for unassigned code points (Cn).
