On Windows, Armenian characters do not display in QtWebKit when using the Arial font, but they do work when using Segoe UI font. However in QTextBrowser it works regardless. Also everything works fine on desktop Linux, even when I installed the Arial font directly from my Windows install.

So it appears that character fallback isn't working correctly.

I've made a test application demonstrating that it works as expected with QTextBrowser, but not with QtWebKit (both QtQuick2 & QWebView.) Just push the button repeatedly and it will print it in the three different views with Arial and Segoe UI alternatively.

It's available by:
