#11529: Show instance of Char should print literals for non-ascii printable charcters -------------------------------------+------------------------------------- Reporter: nushio | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nushio): Dear dfeuer, thank you for pointing out that the `Show Char` is specified in Haskell 2010. I believe the corresponding section is the following: https://www.haskell.org/onlinereport/haskell2010/haskellch16.html#x24-217000... {{{ 16.6 String representations showLitChar :: Char -> ShowS Convert a character to a string using only printable characters, using Haskell source-language escape conventions. For example: showLitChar '\n' s = "\\n" ++ s }}} where "Haskell source-language escape conventions" are defined, in turn, in Section 2.6 https://www.haskell.org/onlinereport/haskell2010/haskellch2.html#x7-200002.6 . Correct me if I'm wrong. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11529#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
