[HarfBuzz] Fwd: Where to report a bug with Tamil text rendering in LibreOffice?

there is a contrib/python hbtestfont that prints out cluster information as well as positions. I tried it for you with:

./runpy scripts/hbtestfont -f "Lohit Tamil" -c taml 0BA4 0BA4 0BCD 0BA4
Processing: /usr/share/fonts/truetype/ttf-indic-fonts-core/lohit_ta.ttf
[72>0@(0.00,0.00)+(20.00,0.00), 227>3@(0.00,0.00)+(20.00,0.00), 72>9@(0.00,0.00)+(20.00,0.00)]

This means that there were 3 clusters in the sequence, which is what you want. So it seems that hbng is doing what you want. Remember, hbng doesn't do anything with cursors, but it does do clustering.

Yours,
Martin
