Devanagari: Unable to get svarita and diirgha svarita to render correctly

aupasana commented 8 years ago

From https://groups.google.com/d/msg/sanskrit-programmers/84SkQLKsFvU/NXE4BA5iBQAJ

We see different behaviour when we reference the noto sans devanagari font from Github, early access and fonts.googleapis.com/css. The dirgha svarita and a few other glyphs only render when we reference the ttf file directly. However, in that case, the normal svarita (on the last two words) should probably be rendered like the second and third lines below. How do we accomplish this?

The latest Noto Sans Devanagari is designed to render the svarita's to the right of other top marks. I am led to believe this is the correct way. The earliest fonts did not care much about supporting Vedic and the svarita and anudatta marks were simply moved out of the way to prevent overlaps. If the top line is displayed with the font from 2014 and the others with fonts from 2012, that would explain the differences. The 2014 fonts contain the complete set of Vedic signs, the 2012 fonts do not.

@marekjez86 are urls mentioned above still maintained?

This was an issue related to the choice of glyphs in the subsetting performed by the Google Fonts API. It appears to now be fixed:
