While testing an issue¹ with XeTeX rendering of Devanagari using
Sanskrit 2003 font², I noticed that the Harfbuzz output for the string
“मन्त्र्यमाण” differs from that of Uniscribe (or ICU), but I know nothing
about Devanagari to tell which is correct, so I’m reporting

I’d first make sure you are using the same ICU version in LibreOffice
and HarfBuzz ICU shaper, I recall ICU LayoutEngine introducing several
bugs in its latest versions.

Dear Khaled Hosny,
Thanks for the new XeTeX.
I atach changes for Visual Studio 2005:
harfbuzz.diff.txt for harfbuzz-0.9.10
xetex.diff.txt for XeTeX.
I think it compiles and runs fine.
Thanks,
Akira

My understanding is that x/y_ppem are used for device tables

Hi Behdad,
While comparing the fallback shaping ICU-based XeTeX with the
HarfBuzz-based one, I noticed that ICU uses the Arabic Presentation
Forms-A ligatures if the font have them unlike HarfBuzz. It is not a big
issue (I don’t even have such font, I striped OT tables from fonts to
test), but it
Hi Behdad,
When (accidentally) testing fonts that has no OpenType tables with
vocalized Arabic text, the fallback glyph positioning gives a funny
Tetris-like patterns. I like it :) but may be HarfBuzz should give up on
fallback positioning if the mark will end up as .notdef.

Hi all,
I’m considering the possibility of adding support for ‘opbd’ feature in
XeTeX, and I have some questions.
The OpenType feature registry description¹ is a bit contradicting, but
my understanding is that ‘opbd’ is a merely user interface shorthand,
and the actual features are ‘ltbd’ and

So I’m asking if HarfBuzz can provide an API to retrieve optical bounds,

if side == left:
