It seems that GHCi is clever enough to decode UTF-8 input, which only serves to confuse System.IO even more.
I get: GHCi, version 6.8.2: http://www.haskell.org/ghc/ :? for help Loading package base ... linking ... done. Prelude> map Data.Char.ord "饁" [39233] and Prelude> map Data.Char.ord "£" [163] but also: % ghci -e 'map Data.Char.ord "饁"' <interactive>:1:21: lexical error in string/character literal at character '\129' but again: % ghci -e 'map Data.Char.ord "£"' [194,163] So GHCi used interactively translates input from the terminal's UTF-8, but outputs truncates output to eight bits. Executing a string with -e, it appears to read byte for byte (which I think was the original behavior at some point). -k -- If I haven't seen further, it is by standing in the footprints of giants
