This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
If you want your Haskell code to have UTF8 text IO then use libraries which have UTF8 text IO.
In case of Prelude with this package only three mechanical steps needed:
In all modules import Prelude explicitly and replace every occurrence of Prelude with UTF8Prelude.
Use the NoImplicitPrelude language extension.
In all modules replace every occurrence of System.IO with System.UTF8IO.
utf8-test tests several functions regarding UTF8 text I/O.
Note: utf8-test creates a file named writeFile_test.txt (5,3K) in the current working directory.
