Regression : The characters of some languages are wrong in fancybrowser demo

Some web pages which were displayed well in fancybrowser demo browser for QtWebKit in version 5.3.1 are displayed wrong now in the same demo browser for version 5.3.2.

For example, the following page (in Tibetan) has the diacritics of some glyphs near the main body of character instead above it : http://bo.wikipedia.org/wiki/%E0%BD%82%E0%BD%99%E0%BD%BC%E0%BC%8B%E0%BD%84%E0%BD%BC%E0%BD%A6%E0%BC%8D

In the following example, the main title of the page and some other texts are not displayed at all, are replaced by squares : http://my.wikipedia.org/wiki/%E1%80%97%E1%80%9F%E1%80%AD%E1%80%AF%E1%80%85%E1%80%AC%E1%80%99%E1%80%BB%E1%80%80%E1%80%BA%E1%80%94%E1%80%BE%E1%80%AC
