Summary ZWJ does not join glyphs properly

Reported 2010-03-25 07:14:39 PDT
Created attachment 51637 [details] Test case and expected output for Safari The zero-width joiner (ZWJ) does not join glyphs properly in the complex font path. (It is ignored in the simple font path: see <a href="https://bugs.webkit.org/show_bug.cgi?id=16131">bug 16131</a>.) Safari (4.0.5, 5531.22.7) does not do the shaping at all. Chromium on Linux does the shaping correctly, but incorrectly displays the ZWJ glyph between the joined characters.

Same issue, I've tested on QWebView, Everything render correctly except text with ZWJ, but Google chrome display them correctly. I've tested on Windows 7(32 bit) & 8(64 bit) Environment: Qt 5.0.1 (mingw47_32)
