Testing illegal Unicode hosing things

[cweb]

I've been testing URLs and noticed that my tests containing illegal Unicode are hosing things, not sure where in the pipeline but it seems to be inside the assert_equals(). I've narrowed down the problem test case to this: http://testcases.org/test/unicode/buith.html

The second test case seems to be the problem, testing an illegal half-surrogate U+D800.

assert_equals(uni, uni2, "U+D800");

where:

var uni = '\uD800\u597d';
var uni2 = '\uFFFD\u597d';

Oddly, the test of 'uni' against itself doesn't hose things:

assert_equals(uni, uni, "U+D800");

The issue is with any failing assertion, actually, and is caused by the location of your testharness.js copy: under js rather than resources. This causes us to iloop here:

        var re = /\/resources\/testharness\.js/;
        var i = 0;
        // Fire remove any preamble that doesn't match the regexp
        while (!re.test(lines[i])) {
            i++
        }

Ah perfect, moving testharness.js to /resources solved it, thanks.
