Synopsis

ShortText type

data ShortText #

Compact representation of short Strings

The data is stored internally as UTF8 in an ShortByteString when compiled against bytestring >= 0.10.4, and otherwise the fallback is to use plain old non-compat '[Char]'.

Note: This type is for internal uses (such as e.g. PackageName) and shall not be exposed in Cabal's API

Since: 2.0.0.2

internal utilities

decodeStringUtf8 :: [Word8] -> String #

Decode String from UTF8-encoded octets.

Invalid data in the UTF8 stream (this includes code-points U+D800 through U+DFFF) will be decoded as the replacement character (U+FFFD).

See also encodeStringUtf8

encodeStringUtf8 :: String -> [Word8] #

Encode String to a list of UTF8-encoded octets

Code-points in the U+D800-U+DFFF range will be encoded as the replacement character (i.e. U+FFFD).
