-Tests that regular expressions treat non-BMP characters as two separate characters. From a Unicode correctness point of view this is wrong, but it is what other browsers do. And given that we store strings as UTF-16, it is also more efficient to implement. Also test some other cases related to UTF-8 and UTF-16.
+This page tests handling of malformed escape sequences.
