New description: The file {{{ #!/usr/bin/env runhaskell main = putStrLn "Hello, world!" }}} works as expected: {{{ C:\Temp>runhaskell hello.hs Hello, world! }}} However, if the file is saved as UTF-8 with a BOM (Windows Notepad, for example, sometimes adds this BOM to files), an error occurs: {{{ C:\Temp>runhaskell hello2.hs hello2.hs:1:1: parse error on input `#!/' }}} I'm using the Haskell Platform 2011.4.0.0. I believe that runhaskell/runghc should handle the presence of a BOM correctly; some Windows programs insert a BOM unbeknownst to the user. This behaviour was observed on Windows XP (32-bit) and Windows 7 (32-bit and 64-bit). -- -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/6016#comment:5> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
