    Description

      Soft hyphens are incorrectly rendered as spaces on linux by QWebView. Run the attached trivial PyQt script which simply creates QWebView and adds some text with soft hyphens in it. The soft hyphens are rendered as spaces. QWebView prints the following errors to console:

      load glyph failed err=6 face=0x1f80c90, glyph=2793

      This behavior is seen on linux, but not on windows. Did not bother to test OS X. Attached a screenshot showing incorrect rendering.
