The stringsearch package provides fast find/replace functionality for Haskell ByteStrings. Does there exist corresponding functionality for the text strings defined in the Data.Text package?

The only approaches I can see at the moment involve encoding to UTF8, using stringsearch, and then converting back—which isn’t really ideal!

    Efficient Boyer-Moore search for Text is implemented in the package out of the box. See the source here: http://hackage.haskell.org/packages/archive/text/0.11.1.5/doc/html/src/Data-Text-Search.html

    Access to this functionality is through the standard Text API — splitOn, breakOn, count, replace, and isInfixOf in particular.
