An efficient packed, immutable UTF-8 backed Unicode text type (both strict and lazy), with a powerful loop fusion optimization framework.

The Text type represents Unicode character strings, in a time and space-efficient manner. This package provides text processing capabilities that are optimized for performance critical use, both in terms of large data quantities and high speed.

The Text type provides character-encoding, type-safe case conversion via whole-string case conversion functions (see Data.Text). It also provides a range of functions for converting Text values to and from ByteStrings, using several standard encodings (see Data.Text.Encoding).

Efficient locale-sensitive support for text IO is also supported (see Data.Text.IO).

These modules are intended to be imported qualified, to avoid name clashes with Prelude functions, e.g.

import qualified Data.Text as T

Relationship to the standard text package

This is a fork of the text package ported which uses UTF-8 instead of UTF-16 as its internal representation.

This release is intended to be API compatible with the text-1.2.3.0 release.

Another package providing an UTF-8 backed Text type with a diffferent cost-model is the text-short package.
