On a minor point, it would probably be better to avoid prefixing names
of constants (e.g. DCVertical). Also, the prefix "get" is usually
reserved for functions that have a monadic effect, so names like
decomposition :: Char -> Decomposition
would be more usual than getDecomposition.
Note that Data.Char already has functions generalCategory, toUpper,
toLower and toTitle, which should work on the full range. It should
probably have majorClass as well.
