#9752: Output unicode characters -------------------------------------+------------------------------------- Reporter: pokiaka | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Keywords: unicode, stderr, | Operating System: Windows errors, output, printing, | Type of failure: Incorrect encoding, utf, utf8 | result at runtime Architecture: Unknown/Multiple | Test Case: Difficulty: Easy (less than 1 | Blocking: hour) | Differential Revisions: Blocked By: | Related Tickets: | -------------------------------------+------------------------------------- When using UnicodeHaskell and having an error with a unicode symbol lurking around, GHC fails to print its name. So e.g. you get a message of an error "In the first argument of (<stderr>: commitBuffer: invalid argument (invalid character)". I am not certain, but I think that the fix would be to `hSetEncoding stderr utf8` before the output is printed. If so, hopefully it should be a quick easy fix. (And perhaps it would be appropriate to do the same for stdout as-well, or just when UnicodeSyntax is on). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9752 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
