Unlikely yes, yet I get the following in GHCi (ghc 6.6.1, the version currently in Debian Sid): > map ord "a" [97] > map ord "ö" [195,182] Funky, isn't it? ;-) Easy! > > Prelude> 'å' == '\229' > True > Prelude> 'å' == Char.chr 229 > True > > Remember, when you type: > Prelude> 'å' > > what you really get is: > Prelude> putStrLn (show 'å') > > So perhaps what is confusing you is the Show instance for Char which > converts Char -> String into a portable ascii representation. Have you tried putting any of this into GHCi (6.6.1)? Any line with 'å' results in the following for me: > 'å' <interactive>:1:2: lexical error in string/character literal at character '\165' > "å" "\195\165" Somewhat disappointing. GHCi 6.8.2 does perform better though. /M
