Hey! Thank you for the PR.

Could you please clarify what issue this PR addresses?

It might look self-evident to you, but it would be good to understand intention. We don’t bring everything from the spec to MDN. Only the parts that are useful for web developers.

Well recently, I was working with strings and Blobs, and wondered what the character encoding was, this information is vital when decoding.

Decoding using the wrong character encoding produces something totally different from the original text.

const bytes = await new Blob(["this is a UTF-16 string that will be converted to UTF-8"]).bytes();
console.log(new TextDecoder("UTF-8").decode(bytes)); // this is a UTF-16 string that will be converted to UTF-8
console.log(new TextDecoder("UTF-16").decode(bytes)); // 桴獩椠⁳⁡呕ⵆ㘱猠牴湩⁧桴瑡眠汩敢挠湯敶瑲摥琠呕ⵆ�
