The issue has to do with the character
\u0fc6 = "TIBETAN SYMBOL PADMA GDAN"
which should appear under the previous character, and appears on the right.
I'm using the same font in both the example that works (in Libre Office) and the one that doesn't (in emacs).
The font I'm using is Tibetan Machine Unicode, available freely at:
Can someone please look at this?
Thanks,
