data EncodingException #

This exception type is thrown whenever something went wrong during the encoding-process.

Constructors

HasNoRepresentation Char

Thrown if a specific character is not representable in an encoding.

data DecodingException #

This exception type is thrown whenever something went wrong during the decoding-process.

Constructors

IllegalCharacter Word8	The sequence contained an illegal byte that couldn't be decoded.
UnexpectedEnd	more bytes were needed to allow a successfull decoding.
OutOfRange	the decoded value was out of the unicode range
IllegalRepresentation [Word8]	The character sequence encodes a character, but is illegal.
