Hi Aditya,
Thanks for the advice. As I am a newby, I'd decided to respond to the list:
I had a look at "char-def.lua" and I think the only thing that needs to be done
is to add
mathname="blacktriangle",
to
[0x25B4]={
adobename="blackuppointingsmalltriangle",
category="so",
description="BLACK UP-POINTING SMALL TRIANGLE",
direction="on",
linebreak="al",
unicodeslot=0x25B4,
},
The unicodeslot is consistent to what I've found in the famous WWW
http://www.fileformat.info/info/unicode/char/25b4/index.htm
Same goes for
[0x25BE]={
category="so",
description="BLACK DOWN-POINTING SMALL TRIANGLE",
direction="on",
linebreak="al",
unicodeslot=0x25BE,
},
with mathname="blacktriangledown" under the assumption you'd like to be
consistent with the naming convention of latex.
Right?
Cheers,
Andreas
