It seems that ghci calls setlocale(LC_ALL,"") or similar, while the compiled code doesn't. I've no idea why that would be, but da...@linux-mkk1:~/Haskell/CafeTesting> cat locl.h void sloc(); da...@linux-mkk1:~/Haskell/CafeTesting> cat locl.c #include <locale.h> #include "locl.h" void sloc(){ setlocale(LC_ALL,""); } main = do setloc (sequence_ . fmap (UTF8.putStrLn . uncurry fmt)) widths where... foreign import ccall unsafe "locl.h sloc" setloc :: IO () fixes it. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
