#9987: GHC refuses to compile a file that starts with a Byte Order Mark (BOM) -------------------------------------+------------------------------------- Reporter: Henk-Jan | Owner: Type: feature request | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.10.1-rc1 Resolution: | Keywords: Operating System: Windows | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by hvr): Currently, GHC's lexer assumes its input to be ASCII or UTF8 (for which a BOM is rather pointless -- as an UTF8 stream doesn't allow for different byteorders). The CP1252 (same with ISO-8859-1 btw) encoding, however, is only compatible for the lowest 128 code-points. I believe the usual recommendation is to use Notepad++ which allows to write UTF8 w/o that gratuitous BOM. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9987#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
