Re: [Haskell-cafe] Unicode pretty-printing

Yes, it's GHC 6.12.3. Character escapes are the least I want to see. As for the locale: $ locale LANG= LC_COLLATE="C" LC_CTYPE="C" LC_MESSAGES="C" LC_MONETARY="C" LC_NUMERIC="C" LC_TIME="C" LC_ALL= Unfortunately, I'm completely lame with locales and googling doesn't help very much to change "C" to something like UTF-8 (Mac, Snow Leopard). But the terminal does support UTF-8 anyway, as the output from my previous message shows (the main function output). On 29 August 2010 11:49, Ivan Lazar Miljenovic wrote:

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.

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.
