+  The `async` contextual keyword must not contain Unicode escape sequences.
+info: |
+  Terminal symbols of the lexical, RegExp, and numeric string grammars are shown
+  in fixed width font, both in the productions of the grammars and throughout this
+  specification whenever the text directly refers to such a terminal symbol. These
+  are to appear in a script exactly as written. All terminal symbol code points
+  specified in this way are to be understood as the appropriate Unicode code points
+  from the Basic Latin range, as opposed to any similar-looking code points from
+  other Unicode ranges.
