or 25BC (the bigger one)
To make it short: I think Hans is correct. From my perspective there is an
error in char-def.lua for blacktriangleleft and secondly the internet page I
have looked this up is not consistent with what is implemented in ConTeXt, both
facts of which lead me into the wrong direction (see below (P.S.), if you are
interested).
Both,
http://www.unicodemap.org/details/0x25B2/index.html
and
http://www.unicodemap.org/details/0x25BC/index.html
look consistent to \blacktriangleright (which I am already using in my
document):
http://www.unicodemap.org/details/0x25B6/index.html
Cheers,
Andreas
P.S.: When I started to look into this I thought it might be possilble to
define some command in the preamble of my document that uses unicode. From
searching the internet I found
http://www-sop.inria.fr/marelle/tralics/doc-b.html
which says The \blacktriangle command is valid only in math mode. Its
translation is moblacktriangle;/mo (Unicode U+25B4, ▴).
However, there indeed is a problem (which I have not spotted in the first
place). I had a look at char-def.lua which at first confirmed my impression on
using small triangels:
[0x25B8]={
category=so,
description=BLACK RIGHT-POINTING SMALL TRIANGLE,
direction=on,
linebreak=al,
mathclass=bin,
mathname=blacktriangleleft,
unicodeslot=0x25B8,
},
However, this is not consistent with what you can find on the internetpage from
above, since it 0x25B8 should be blacktriangleright
The \blacktriangleright command is valid only in math mode. Its translation is
moblacktriangleright;/mo (Unicode U+25B8, ▸).
Secondly, the \triangleleft, which I have not used before, does not work (at
least for me ConTeXt ver: 2012.07.10 09:52 MKIV fmt: 2012.7.15 int:
english/english):
simple example:
\starttext
$\blacktriangleleft$ % does not appear
$\blacktriangleright$ % works
\stoptext
For the blacktriangleright we have:
[0x25B6]={
adobename=blackrightpointingtriangle,
category=so,
cjkwd=a,
description=BLACK RIGHT-POINTING TRIANGLE,
direction=on,
linebreak=ai,
mathclass=bin,
mathname=blacktriangleright,
unicodeslot=0x25B6,
},
which is _not_ consistent with The \blacktriangleright command is valid only
in math mode. Its translation is moblacktriangleright;/mo (Unicode U+25B8,
▸).
However, looking at http://www.unicodemap.org/details/0x25B6/index.html and
given the fact that blacktriangleright works nicely, I'd assume that Hans is
correct and it indeed is not the small ones but the big tirangles.

Re: [NTG-context] math symbol: blacktriangle
Hi,
Thanks Hans. It works for me :) Relating the output (\blacktriangleright and
\blacktriangle) to some figure I have created with latex + tikz I do not see
any difference.

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
