Inset starts with number token which lowest byte equals to this prefix. Tokens after this token considered
as inset input chunks rather normal tokens. The inset supposed to be processed by appropriate lexer. The token itself is used as inset format identifier. The inset input ends with UC_TOKEN_INSET_END
token. The inset bounds themselves are control tokens to be ignored.
Inset expected at value position and nowhere else. E.g. it can't be inserted into the middle of a string.
