#8118: <stdout>: commitAndReleaseBuffer: invalid argument (invalid character) -------------------------------------+------------------------------------- Reporter: guest | Owner: Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: #5666 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): OK, thank you for confirming. As I [https://ghc.haskell.org/trac/ghc/ticket/7593#comment:6 noted] in #7593, just changing the encoding to `utf8` is a sufficient fix for `mintty`, but it's not enough for `cmd.exe`. For the latter, the only solution I've found was to use native Windows console API functions such as `WriteConsoleW` and `ReadConsoleW`. This only works for `stdin`/`stdout`, though, and not general file IO. I imagine it would be a pretty significant time investment redesigning Haskell IO to use Windows API calls everywhere, though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8118#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
