[back to package description]Unicode Transforms
Fast Unicode 8.0 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
