The API of this module is unstable and not meant to be consumed by the general public. If you absolutely must depend on it, make sure to use a tight upper bound, e.g., base < 4.X rather than base < 5, because the interface can change rapidly without much warning.
Simple UTF-8 codecs supporting non-streaming encoding/decoding. For encoding where codepoints may be broken across buffers, see GHC.IO.Encoding.UTF8.
This is one of several UTF-8 implementations provided by GHC; see Note [GHC's many UTF-8 implementations] in GHC.Encoding.UTF8 for an overview.
utf8DecodeCharAddr# :: Addr# -> Int# -> (# Char#, Int# #) Source
Decode a single character at the given Addr#.
utf8DecodeCharPtr :: Ptr Word8 -> (Char, Int) Source
Decode a single codepoint starting at the given Ptr.
utf8DecodeCharByteArray# :: ByteArray# -> Int# -> (# Char#, Int# #) Source
Decode a single codepoint starting at the given byte offset into a ByteArray#.
utf8DecodeByteArray# :: ByteArray# -> [Char] Source
utf8DecodeForeignPtr :: ForeignPtr Word8 -> Int -> Int -> [Char] Source
utf8CountCharsByteArray# :: ByteArray# -> Int Source
utf8CompareByteArray# :: ByteArray# -> ByteArray# -> Ordering Source
utf8EncodePtr :: Ptr Word8 -> String -> IO () Source
utf8EncodeByteArray# :: String -> ByteArray# Source
utf8EncodedLength :: String -> Int Source
