#5518: Some unicode symbols are not allow in literal characters or strings ---------------------------------+-------------------------------------- Reporter: ertai | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.0.3 Resolution: fixed | Keywords: Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+-------------------------------------- Comment (by joeyh): Similarly, with ghc 8.2.2 (debian), this is not accepted: main = putChar '🥖' That's U+1F956 baguette. ghc says: lexical error in string/character literal at character '\129366' My system is fully utf-8 enabled and the original problem character works ok. Guess this is just lag getting the unicode character tables updated. However, while it seems reasonable for ghc to not let me define a function eg (🥖) = () since it doesn't know what kind of symbol baguette is, it seems much less reasonable to not accept any unicode inside a string. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5518#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
