The combinator for character literals is at https://github.com/susisu/loquat/blob/master/packages/token/lib/token.js#L245-L339. Quirks: x and o are lowercase-only for escapes and case-insensitive for integers, only 26 control characters can be escaped with the \\^ form, and string and char literals disallow a strange range of literal control characters."
