decodeUTF8 :: ByteString -> [Word32] Source #
encodeUTF8 :: [Word32] -> ByteString Source #
encodeUTF8' :: [Word32] -> [[Word8]] Source #
Word32s not representing valid UTF8 chars are dropped.
hPutUTF8Ln :: UTF8 a => Handle -> a -> IO () Source #
readUTF8File :: UTF8 a => FilePath -> IO a Source #
writeUTF8File :: UTF8 a => FilePath -> a -> IO () Source #

hGetUTF8Line :: UTF8 a => Handle -> IO a Source #
hGetUTF8Contents :: UTF8 a => Handle -> IO a Source #
hGetUTF8 :: UTF8 a => Handle -> Int -> IO a Source #
Be careful that you're sure you're not chopping a UTF8 char in two!
hGetUTF8NonBlocking :: UTF8 a => Handle -> Int -> IO a Source #
Same warning as for hGetUTF8
unflipUTF8 :: UTF8 a => a -> a Source #
ghci> putUTF8Ln $ (unflipUTF8 . flipUTF8) "[?np_bs!]" [?np_bs!]
