#7650: can't use combining characters in identifiers -------------------------+-------------------------------------------------- Reporter: guest | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.6.1 | Keywords: Os: Linux | Architecture: x86 Failure: None/Unknown | Blockedby: Blocking: | Related: -------------------------+-------------------------------------------------- ghc doesn't let me use combining characters in unicode identifiers. Here's a test case with U+308 (COMBINING DIAERESIS) but it affects all accents: {{{ % cat comb.hs main = print spın̈alTap where spın̈alTap = 11 }}} {{{ % ghc comb.hs [1 of 1] Compiling Main ( comb.hs, comb.o ) comb.hs:1:18: lexical error at character '\776' }}} (This is actually with ghc 7.6.2 but the `Version` drop-down only goes up to 7.6.1.) -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7650 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
