An efficient packed, immutable 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. It also provides a range of functions for converting Text values to and from ByteStrings , using several standard encodings.

Efficient locale-sensitive support for text IO is also supported.

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

import qualified Data.Text as T
