[HarfBuzz] Question on converting UTF-8 codepoints to complex glyphs

[Paul Daughetee]

I'm new to HarfBuzz and attempting to use it for converting a UTF-8 string that contains one or more sets of codepoints that should combine to form single complex glyphs to the correct string of glyphs. I've followed numerous examples and they all lead me to the point where I use hb_buffer_get_glyph_infos to get what I thought would be a hb_glyph_info object that contains the codepoints for the glyphs I seek. So my first question is as follows. Is that what I should be getting? I ask because I'm not getting what I would expect to get. I can't even successfully get a complex glyph to represent the combination of the letter A and the grave accent. So if I'm just confused as to how or what HarfBuzz does, please help me find a better path. Thanks!
