| Behavior when pattern is a string describing a valid pattern (unicode) |

| 5. Return ? RegExpInitialize(O, P, F). |
| |
| 21.2.3.2.2 Runtime Semantics: RegExpInitialize |
| |
| 6. If F contains "u", let BMP be false; else let BMP be true. |
| 7. If BMP is true, then |
| a. Parse P using the grammars in 21.2.1 and interpreting each of its |
| 16-bit elements as a Unicode BMP code point. UTF-16 decoding is not |
| applied to the elements. The goal symbol for the parse is Pattern. |
| Throw a SyntaxError exception if P did not conform to the grammar, if |
| any elements of P were not matched by the parse, or if any Early |
| Error conditions exist. |
| b. Let patternCharacters be a List whose elements are the code unit |
| elements of P. |
