             Bug #: 39481
           Summary: Add  <at> font-face for the most important fonts that
                    supports unicode

There should be  <at> font-face definitions for the most important fonts that
supports unicode, at least for those that impacts the content language. It
should also be fairly easy to extend the set with additional definitions if it
is important for some specific content.

A separate bug could be to identify the fonts necessary to support
Wikipedia/Wiktionary. At least the Unicode-variants of the most common fonts
should be available.
