#10889: Compiled software can not read UTF-8 characters using readFile when run via Upstart -------------------------------------+------------------------------------- Reporter: SiXoS | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: invalid | Keywords: Operating System: Linux | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by nomeata): * status: new => closed * resolution: => invalid Comment: This is expected. I assume that under upstart, programs are run without a locale being set, so your Haskell program does not know what encoding to use when reading that file, defaults to (I believe) `ascii` and fails to decode your file. There are basically two solution: * Change the upstart script to set a locale (e.g. `LANG=C.utf-8`). * Change the program to explicitly set the encoding you want it to use (see `hSetEncoding` in `System.IO`) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10889#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
