+description: >
+  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.
