I haven't seen ghc's code, but I bet it uses something like `let (digits, str') = span isDigit str in chr (read digits) : parse str'` to process escape sequences in string/character literals. This is broken because `isDigit` returns `True` for a lot of non-`['0'..'9']` characters, such as subscripts, Thai digits, double-wide digits, etc.",bug,closed,normal,6.10.1,Compiler (Parser),6.8.2,fixed,,,Linux,Unknown/Multiple,,Unknown,,,,
