[HarfBuzz] I wonder why glyph 'uni0647' is not substituted with the one at 0xFEE9('uni06BE.fina') in Tahoma font

[Jonathan Kew]

It's not really clear to me what you're asking or expecting. There are 
several instances of U+0647 in your string.... looks like they should be 
one initial, two medial and one final.

What exact version of harfbuzz and of tahoma is involved? The result I'm 
seeing here matches your MSWord image. That's correct, isn't it?
