pipes-text
This package follows the rule:
pipes-text : pipes-bytestring :: text : bytestring
The division of three modules, Pipes.Text , Pipes.Text.Encoding and Pipes.Text.IO has more or less the significance it has in the text library.
Note that the module Pipes.Text.IO uses version 0.11.3 or later of the text library. (It thus works with the version of text that came with the 2013 Haskell Platform. To use an older text, install with the flag -fnoio
