Thanks for getting back to me. I was imprecise, by UTF8 characters I mean Unicode. My source files are UTF8-encoded, and Haskell reads them fine, it only has problems outputting them in a readable way. At this point I'm not talking of any I/O besides plain console output.
How are you outputting them? Unless you use a textual String I/O function with GHC 6.12, then by default showing a String will print it with escape characters for non-latin characters.
Prelude> :load utest.hs [1 of 1] Compiling Main ( utest.hs, interpreted ) Ok, modules loaded: Main. *Main> main это тест *Main> runTestTT test1 ### Failure: fail expected: *** Exception: <stderr>: hPutChar: invalid argument (Illegal byte sequence)
Hmmm... if you are using GHC 6.12, what's your locale? I've only seen error messages like that when using something with a different encoding than your locale. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
