Module      : Z.Data.Text
Description : Unicode text processing

Stability   : experimental
Portability : non-portable

A 'Text' wrap a 'Bytes' which will be interpreted using UTF-8 encoding. User should always use 'validate' \/ 'validateMaybe' to construt a 'Text' (instead of using construtor directly or coercing), otherwise illegal UTF-8 encoded codepoints will cause undefined behaviours.

This library also provide simple unicode processing based on <https://github.com/haskell-Z/utf8rewind/ utf8rewind>,
see 'normalize', 'caseFold' (current using unicode 13 databases).
