<br>
P.S. There's actually a third class of bug that is clearly visible in<br>
the table at the top of my document, but which I didn't mention<br>
explicitly: XeTeX won't typeset one of the Devanagari combining<br>
characters in isolation without adding a prothetic dotted circle<br>
(U+25CC).<br>
<br>
===========================================================================<br>
<br>
On a lark, I've been experimenting with typesetting Vedic Sanskrit,<br>
specifically verses from the Ṛg-Veda, using the Murty Hindi font from<br>
Tiro Typeworks. So far, XeTeX works beautifully, with two exceptions<br>
involving the Vedic udatta and anudatta accent marks:<br>
<br>
a) They don't attach properly to the Devanagari digits 1 and 3, and<br>
<br>
b) They don't combine properly with the candrabindu, anusvara, and<br>
visarga signs.<br>
<br>
luaTeX does render these correctly, so it doesn't appear to be a<br>
problem with the font itself.<br>
<br>
I've included a zip file with a test file and sample output from<br>
luaTeX and XeTeX.<br>
<br>
Is this a bug, or am I missing something obvious?<br>
