- unpack :: (UnSnoc xs ~ (,) ys y, Superset "r-UNICODE.D76" y, encs ~ RemoveRs ys, AllEncodeInto "r-UNICODE.D76" encs) => Enc xs c Text -> Enc xs c String
- utf8Promote :: Enc xs c Text -> Enc (Snoc xs "r-UTF8") c Text
- utf8Demote :: UnSnoc xs ~ (,) ys "r-UTF8" => Enc xs c Text -> Enc ys c Text
- d76Promote :: Enc xs c Text -> Enc (Snoc xs "r-UNICODE.D76") c Text

pack :: (UnSnoc xs ~ (,) ys y, Superset "r-UNICODE.D76" y, encs ~ RemoveRs ys, AllEncodeInto "r-UNICODE.D76" encs) => Enc xs c String -> Enc xs c Text Source #
This assumes that each of the encodings in xs work work equivalently in String and Text.
unpack :: (UnSnoc xs ~ (,) ys y, Superset "r-UNICODE.D76" y, encs ~ RemoveRs ys, AllEncodeInto "r-UNICODE.D76" encs) => Enc xs c Text -> Enc xs c String Source #
This assumes that each of the encodings in xs work work equivalently in String and Text.
utf8Promote :: Enc xs c Text -> Enc (Snoc xs "r-UTF8") c Text Source #
Text is automatically "r-UTF8" encoded
Adding "r-UTF8" annotation simply adds type level interpretion requirement that Text is treated
as UTF8. The internals of Text (currently UTF-16) are not relevant and utf8Promote is implemented
as id. This is not the same as encoding Word8 layouts into Char-s.
This, in typed-encoding terminology, would be "enc-UTF8", not @"r-UTF8".
