Description

U+FFFD is the Unicode replacement character inserted when the input bytes can not be decoded.

For parsers based on RIOT and its text tokenizer, warn if this character is seen in strings, IRIs, blank node labels and prefix names.

If \uFFFD is seen, (escaped Unicode character), do not warn.
