+description: >
+ Support for surrogate pairs within patterns match by the CharacterClass Atom
+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) and return its Matcher result.
+
+ Runtime Semantics: CharacterSetMatcher Abstract Operation
+
+ 1. Return an internal Matcher closure that takes two arguments, a State x and
+ a Continuation c, and performs the following steps when evaluated:
+ [...]
+ d. Let cc be Canonicalize(ch).
