Hi,
I have a Haskell source file encoded in utf-8. Inside that source, I have literal strings that I'd like to pass to a C function.
withCString does the job well until I tried to use the double-quote character ". I get /usr/lib/ghc-6.10.1/ghc: `@: Bad font file format (even when using (chr 34) instead).
I didn't understand the reason of this behavior (since the double quote is just ascii) but tried to use useAsCString but coudn't do it. I can ByteString.Char8.pack my string but the problem remains. I tried to use IConv but it uses UTF8.ByteString and I don't know how to make the conversion so I can use useAsCString or withCString.
Bulat asked me a minimal example. I cannot come with the same behavior with ghc --make and the attached code. Maybe it is showed inside ghci. Anyway, I'd like to get my utf-8 string to C but in ascii (or latin1). How can do this ?
