hb_buffer_set_direction (fBuffer, HB_DIRECTION_LTR);<br>
hb_buffer_add_utf32 (fBuffer, "١٢"); // pseudo code, of course<br>
<br>
then the glyphs are presented in the wrong order to the font features. You can see this with the font available at <<a href="http://fonts.qurancomplex.gov.sa/?page_id=42" rel="noreferrer" target="_blank">http://fonts.qurancomplex.gov<wbr>.sa/?page_id=42</a>>. It's intended for the Quran (and only for the Quran; word doc at the same URL), and ligates sequences of digits for the end of ayah. The example above displays "end of ayah 21".<br>
<br>
I am using a slightly old version of Harfbuzz, so may be this has been fixed?<br>
<br>
Thanks,<br>
Eric.<br>
