Nice! Should this effort be coordinated with Unicode-related encoding/decoding? See the Encoding class in Twan van Laarhoven's CompactString library: http://twan.home.fmf.nl/compact-string/ and Johan Tibell's UnicodeByteString proposal: http://haskell.org/haskellwiki/UnicodeByteString There was a recent discussion about these, mostly the latter: http://www.haskell.org/pipermail/haskell-cafe/2007-September/032195.html I hate to keep bringing up serpents, but note that Python has a nice codec abstraction that provides efficient encoding and decoding of character encodings, data encodings, data compression, etc., all with the same interface. You can attach these things to file handles, or apply them to strings. Makes sense to me. Thanks, Yitz

Yes, I somewhat followed the beginning of that discussion but my Unicode-fu isn't very strong. If you have concrete suggestions for changes to the API then please let me know. I have vague plans of writing a uuencode/uudecode in Haskell so that might bring up some issues with the current API.

It would be great to see something equally unified in Haskell in the future. /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus．therning＠gmail．com http://therning.org/magnus
