Re: Analysis of combining diacritics support

The positioning issue you see is likely a problem that T doesn't have a 
cedilla anchor in Serif. Normally an easy fix.

That's why renderers should have fall-back options (like Qt has). 
Usually these fall backs will give less optimal results, but a lot 
better than nothing at all.

Well, we would need them only in one rare case (when we emphasize 
the "ij" sound, like "íj́" ) As a result the accent on the j is usually 
dropped, so it becomes "íj", but official spelling rules want both 

Anyway, there are many languages with Latin script that are much worse 
of (a lot of African languages for example), since combining diacritics 
are needed in an awful lot of other languages. Because font foundries 
select their character sets based on the market demand, they don't see 
a lot of merit in adding glyphs and features that are only needed 

So, that's basically something we should exploit with free/open fonts, 
to give us the lead in these areas.
