表单是以Windows-1252编码提交的
我在Firefox网络控制台的JS标签中收到以下警告（ Ctrl + Shift + K ）
I am getting the following warning in the JS tab of the Firefox web console (Ctrl + Shift + K)
表单是在windows-1252编码中提交的，不能编码
所有Unicode字符，因此用户输入可能会损坏。为了避免这个
问题，应该更改页面，以便在
UTF-8编码中提交表单，通过将页面本身的编码改为UTF-8或者通过指定accept-charset = utf-8。 @http：// localhost：8080 / myapp / login
html确实使用utf-8编码，如下：
The html does use the utf-8 encoding explicitly, like so:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />;
html（实际上是Freemarker模板）文件以前在Windows机器上。因此，我使用recode实用程序（如此处）将它们重新编码为utf-8。但我仍然看到同样的警告。
The html (actually Freemarker templates) files were previously on a Windows machine. So I recoded them to utf-8 using the recode utility as suggested here. But I still see the same warning.
我在这里缺少什么？

基于注释，很明显，服务器在HTTP头中指定编码为ISO-8859-1。您无法在HTML中为文档本身覆盖此内容。不过，您可以使用 accept-charset = utf-8 /forms.html#h-17.3> form 标记指定表单数据提交的字符编码。
Based on the comment, it seems obvious that the server specifies the encoding as ISO-8859-1 in HTTP headers. You cannot override this in HTML for the document itself. You can, however, use the accept-charset=utf-8 attribute in the form tag to specify the character encoding of the form data submission.
要更改HTTP头，您需要在服务器级别执行某些操作。这可能意味着创建或编辑.htaccess文件或其他文件。
To change the HTTP headers, you need to do something at the server level. This may mean creating or editing a .htaccess file, or something else.
Accept-Encoding 头与此无关。它不指定字符编码，但指定数据的传输编码。
P.S. The Accept-Encoding header is unrelated to this. It does not specify character encoding but a transfer encoding for the data.
