Here’s how to convert between byte, string, and character types in Haskell:
| Function | Type |
|---|---|
| encodeUtf8 | Text -> ByteString |
| unpack | Text -> String |
| decodeLatin1 | ByteString -> Text |
| decodeUtf8With lenientDecode | ByteString -> Text |
| BC.unpack | ByteString -> String |
| UTF8.toString | ByteString -> String |
| B.unpack | ByteString -> [Word8] |
| UTF8.fromString | String -> ByteString |
| pack | String -> Text |
| w2c | Word8 -> Char |
| B.pack | [Word8] -> ByteString |
| c2w ❌ partial | Char -> Word8 |
| BC.pack ❌ partial | String -> ByteString |
| BSC.string ❌ stops streaming | String -> BSC.ByteString |
Note that Char is finite:
toEnum 10000000 :: Char
*** Exception: Prelude.chr: bad argument: 10000000
