portable encoding/decoding without going via a handle

Hi, I need to convert directly between different string encodings, rather than just using a particular encoding when reading from/writing to a Handle. I'm aware of the following options, but they have a few problems: - text-icu: not easily usable on Windows as it requires libicu - text: just handles utf8/16/32 - iconv: POSIX only It seems like GHC's TextEncoding has the necessary low-level functionality (http://hackage.haskell.org/packages/archive/base/latest/doc/html/GHC-IO-Enco...), but I can't find any high-level interface for directly transcoding between String/Bytestring/Text. Am I missing something, or would this be a useful addition as a separate library? Cheers, Ganesh
