Hi All,
I am using HarfBuzz 2.10 for Indic languages in my application but
failed to get correct substituted glyph from hb_shape API for Bengali
text having vowels like e (U+09c7), ai (U+09c8), o (U+09cb), au (U+09cc)
in between the words in any Bangali font contains Bengali glyphs like
-Nirmala UI Regular font.
These glyphs are substituted fine if these are at the start of word and
if these glyphs are in between word then it’s Shirorekha glyph should be
return by the shaping API.
Actual result-
Expected result-
I have also tested same with latest (2.5.0) HarfBuzz library but no luck
result.
Kindly suggest whether the issue is in hb_shape API or in the fonts or I
have to do something at my end to get desire result.
It's helpful if you specify the exact character sequence involved when
reporting a problem. From your actual/expected images, I'm assuming that
word is <U+0986, U+09AC, U+09C7, U+09A6, U+09A8>.
If that sequence is right, then AFAICS it works as expected with the
Nirmala font: the result I get looks like your "expected" image.
So I guess the problem is somewhere in your code. HarfBuzz shapes this
text and font correctly.
