You could use:
你可以使用：
contentType:"application/x-javascript; charset:ISO-8859-1"

By giving the content type explicitly during ajax call as below may allow you to override the default content type.
通过在 ajax 调用期间显式提供内容类型，如下所示可能允许您覆盖默认内容类型。
$.ajax({
data: parameters,
type: "POST",
url: ajax_url,
timeout: 20000,
contentType: "application/x-www-form-urlencoded;charset=ISO-8859-15",
dataType: 'json',
success: callback
});
You would also have to specify the charset on the server.
您还必须在服务器上指定字符集。
Ex: for php
例如：对于 php
<?php header('Content-Type: text/html; charset=ISO-8859-15'); ?>
I hope this may help you.
我希望这可以帮助你。

It seems the charset cannot be changed anymore – $.ajaxdocs states:
似乎字符集不能再更改了——$.ajax文档说明：
The W3C XMLHttpRequest specification dictates that the charset is always UTF-8; specifying another charset will not force the browser to change the encoding.
W3C XMLHttpRequest 规范规定字符集始终为 UTF-8；指定另一个字符集不会强制浏览器更改编码。

See section 4.5.6.4.4.3 of the XHR spec: https://xhr.spec.whatwg.org/#the-send()-method
请参阅 XHR 规范的第 4.5.6.4.4.3 节：https://xhr.spec.whatwg.org/#the-send()-method
If contentTypeRecord is not failure, contentTypeRecord's parameters["charset"] exists, and parameters["charset"] is not an ASCII case-insensitive match for "UTF-8", then:
Set contentTypeRecord's parameters["charset"] to "UTF-8".
如果 contentTypeRecord 没有失败，则 contentTypeRecord 的参数 ["charset"] 存在，并且参数 ["charset"] 不是“UTF-8”的 ASCII 不区分大小写匹配，则：
将 contentTypeRecord 的参数 ["charset"] 设置为 "UTF-8"。
The spec forces browsers to always send as UTF-8.
该规范强制浏览器始终以 UTF-8 格式发送。
You may however, use the fetchAPI. Since it's not an XHR, posting using fetch will honour your encoding.
但是，您可以使用fetchAPI。由于它不是 XHR，因此使用 fetch 发布将尊重您的编码。
fetch(url, {
method: 'POST',
headers: {
'Content-Type': `text/plain; charset=${yourCustomEncoding}`
},
body
}).then(...
