[HarfBuzz] tegulu

You probably saw this string today on unicode@:

      ।।ఓం పయోఽంబువచ్చేత్ తత్రాపి ఓం।। 3  

hb-view from master and pango-view from 1.34.0 were able to render that
w/o a dotted circle between the ఽం when I used Pothana2000.

With every other font returned by fc-list :lang=te|sort they rendered a
dotted circle between those two glyphs.

Emacs, using libotf and m17n-lib, rendered it correcly.

(Unlike hb-view, pango-view fell back for the four instances of ।.
I presume that is by design.)

For those who don't utf-8, that pair of chars is:

     u+0C3D TELUGU SIGN AVAGRAHA
     U+0C02 TELUGU SIGN ANUSVARA
