HTML5 是否允许使用 UTF-16 编码外部脚本？
Does HTML5 permit encoding external scripts in UTF-16?
HTML 标准要求¹对 HTML 文档使用 UTF-8 编码。
是否允许对外部加载的脚本使用其他编码？
<script src="/script1.js">
<script type="module" src="/script2.mjs">
这些脚本将以 UTF-16 而不是 UTF-8 编码，并且将由具有 header Content-Type: text/javascript; charset=UTF-16 的 Web 服务器提供。此设置是否符合 HTML 规范？
The HTML standard requires the use of the UTF-8 encoding for HTML documents
不，不是。它 更喜欢 UTF-8，但您可以使用您想要的任何其他字符集，只要您在适当的 <meta> 元素中明确声明它。参见 Declaring character encodings in HTML。
Does it permit the use of other encodings for externally loaded scripts?
<script> 元素有一个 charset attribute，虽然这已被弃用，取而代之的是 Content-Type HTTP header 的 charset 属性，当脚本被检索。如果 charset 出现在 <script> 中，它必须匹配 Content-Type 的 charset。如果未指定 charset，则假定 HTML 的字符集。
JavaScript 模块看起来像 HTML5 permits different encodings for regular scripts and mandates UTF-8。
To fetch a classic script given a url, a settings object, some options, a CORS setting, and a character encoding, run these steps. The algorithm will asynchronously complete with either null (on failure) or a new classic script (on success).
[...]
If response's Content Type metadata, if any, specifies a character encoding, and the user agent supports that encoding, then set character encoding to that encoding (ignoring the passed-in value).
Let source text be the result of decoding response's body to Unicode, using character encoding as the fallback encoding.
[...]
To fetch a single module script, given a url, a fetch client settings object, a destination, some options, a module map settings object, a referrer, and a top-level module fetch flag, run these steps. The algorithm will asynchronously complete with either null (on failure) or a module script (on success).
