Comment 4 for bug 1002757

A possible solution is to replace some pango font family names with generic css equivalents whilst still using those pango fonts
Sans -> sans-serif
Serif -> serif
Monospace -> monospace

One issue is that existing files with those fonts (Sans , Serif, Monospace) will see the warning (!) in the text toolbar about unknown font, however the correct font should be rendered.

Any thoughts ?
