I like how the spec defines character classes by just passing the buck to Unicode ===== Forbidden Characters Forbidden characters are Unicode scalar values with general category Control, Surrogate, and Unassigned. Forbidden characters must not appear in the source text. White Space White space characters are those Unicode characters with the Whitespace property, including line terminators.
