https://github.com/whatwg/encoding/commit/8360f775c8df145f649047c7d59c5ff733ade112 removed support for UTF-16 in TextEncoder. We should make our implementation reflect the spec change.

-----------------------------------------------------------------

Thank you!

(I'm a bit uneasy about not throwing if there's an argument to the constructor that's not an ASCII case-insensitive match for the string string "utf-8", but that's really a spec concern, since the patch implements the spec.)

Do we need this function if it has just one caller?

I'd prefer

section.encodings.forEach(function(encoding) {
    if (encoding.name !== 'replacement') {
        test(function() {
            assert_equals(new TextDecoder(encoding.name).encoding, encoding.name);
        }, "Encoding argument supported for decode: ' + encoding.name);
    }

    test(function() {
        assert_equals(new TextEncoder(encoding.name).encoding, 'utf-8');
    }, "Encoding argument not considered for encode: ' + encoding.name);
});

Maybe not. Merged with the caller.
