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. 25 26 On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". 27 28 29 PASS /./.exec(surrogatePair).toString().length is 1 30 PASS /\D/.exec(surrogatePair).toString().length is 1 31 PASS /\S/.exec(surrogatePair).toString().length is 1 32 PASS /\W/.exec(surrogatePair).toString().length is 1 33 PASS /[^x]/.exec(surrogatePair).toString().length is 1 34 35 PASS /.{1,2}/.exec("!!" + String.fromCharCode(0xA1)).toString().length is 2 36 PASS /./.exec("") is null 37 38 PASS successfullyParsed is true 39 40 TEST COMPLETE 41 42
