Description Khaled Hosny 2008-01-19 12:50:11 PST 
WebKitGtk doesn't respect the font specified in html files, it always use the same font for rendering Arabic regardless of the specified font, even if it has Arabic glyphs. More ever, choosing a font that doesn't have Latin glyphs causes the English text to be rendered as white spaces or boxes.

Thanks for the detailed bug description.

The lack of integration between the WebKit Pango text renderer and the font selection system is the cause of the Arabic text always using a default font. The simple fix for this depends on the patch in #15229 landing.

The block carets for western text may be related to an issue in the simple text path, bug #16792.

Fixed in r36309 for the "FreeType" backend I believe. Please re-open if the issue persists.
