Instances:
ByteString, String
, [Word32], [Word]
, [Int32], [Int]
countUTF8 :: ByteString -> [Int] Source
Lengths in Word8s
decodeUTF8 :: ByteString -> [Word32] Source
encodeUTF8 :: [Word32] -> ByteString Source
encodeUTF8' :: [Word32] -> [[Word8]] Source
Word32s not representing valid UTF8 chars are dropped.
withUTF8 :: UTF8 a => a -> (ByteString -> b) -> b Source
hPutUTF8Ln :: UTF8 a => Handle -> a -> IO () Source
readUTF8File :: UTF8 a => FilePath -> IO a Source
writeUTF8File :: UTF8 a => FilePath -> a -> IO () Source
appendUTF8File :: 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!
unflipUTF8 :: UTF8 a => a -> a Source
ghci> putUTF8Ln $ (unflipUTF8 . flipUTF8) "[?np_bs!]" [?np_bs!]
