Documentation

data LitChar

Represents a character in a literal. Although encoded characters are allowed to have any value, typically they will not include most ASCII printable characters. In other words A is more likely than %41.

Constructors

Encoded Word8

This deliberately is not case sensitive. The tokens %aa and %AA are both represented as Encoded 0xAA.

Unencoded Char

This assumes that the character passes the isLiteral predicate. You should prefer using makeUnencoded to create these values.
