Fast Unicode 9.0 normalization in Haskell (NFC, NFKC, NFD, NFKD).

What is normalization?

Unicode characters with adornments (e.g. Á) can be represented in two different forms, as a single composed character (U+00C1 = Á) or as multiple decomposed characters (U+0041(A) U+0301( ́ ) = Á). They are differently encoded byte sequences but for humans they have exactly the same visual appearance.

A regular byte comparison may tell that two strings are different even though they might be equivalent. We need to convert both the strings in a normalized form using the Unicode Character Database before we can compare them for equivalence. For example:

>> import Data.Text.Normalize
>> normalize NFC "\193" == normalize NFC "\65\769"
True
