Literal astral symbols within inverted CharacterClass.
info: |
The production Atom :: CharacterClass evaluates as follows:
1. Evaluate CharacterClass to obtain a CharSet A and a Boolean invert.
2. Call CharacterSetMatcher(A, invert, direction) and return its Matcher result.
Runtime Semantics: CharacterSetMatcher ( A, invert, direction )
1. Return an internal Matcher closure that takes two arguments, a State x and
a Continuation c, and performs the following steps:
[...]
f. Let cc be Canonicalize(ch).
g. If invert is false, then
[...]
h. Else,
i. Assert: invert is true.
ii. If there exists a member a of set A such that Canonicalize(a) is cc,
return failure.
