+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).
+     [...]
