+description: Extensions to ClassEscape
+info: |
+    ClassEscape[U] ::
+        b
+        [+U] -
+        [~U] c ClassControlLetter
+        CharacterClassEscape
+        CharacterEscape[?U]
+
+    ClassControlLetter ::
+        DecimalDigit
+        _
+
+    The production ClassEscape :: c ClassControlLetter evaluates as follows:
+
+    1. Let ch be the character matched by ClassControlLetter.
+    2. Let i be ch's character value.
+    3. Let j be the remainder of dividing i by 32.
+    4. Let d be the character whose character value is j.
+    5. Return the CharSet containing the single character d.
