如何使用 utf-8 编码在 Qt5 WebEngineView 中加载 HTML 页面？

Question

I have an html page, which I am loading into my Qt5 application using QWebEngineView like this:

QWebEngineView* webEngineView = new QWebEngineView();
webEngineView->setUrl("index.html");

I use UTF-8 characters in my html file, such as "…" (#x2026; in html), which show up as "?" in the application.

The html file contains <meta http-equiv="Content-Type" content="text/html; charset=utf-8" and I have tried using webEngineView->settings()->setDefaultTextEncoding("utf-8"); to no avail.

Can anyone help me display these characters?

I turns out that the issue was not in the setUrl() method, but in a localisation function I had in my JS file. That function was explicitly setting the encoding to ASCII instead of UTF-8.

The setUrl() method of QWebEngineView seems to load the html file with the correct encoding without it being explicitly specified in the C++ code.
