Dear all, The \blacktriangle and \blacktriangledown symbol seem to be missing, though \blacktriangleright and \...-left are defined. Is there a quick way to add missing symbols by myself from the knowledge of Unicode / XML identifier (http://www-sop.inria.fr/marelle/tralics/doc-b.html)? Cheers, Andreas

For opentype math fonts, have a look at char-def.lua. To add missing symbols, you need to add appropriate fields in the lua table. The hard part is verifying the symbol to unicode slot mapping (the list at tralics is not always consistent with the ams list that is used by unicode-math package). If you know the right mappings, add a patch to char-def.lua and send it to the list (or the dev-context list); otherwise, just send the mappings and I can add them to the lua table. Aditya
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 On Jul 17, 2012, at 7:39 PM, Aditya Mahajan wrote:

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 <mo>▴</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 <mo>▸</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 <mo>▸</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.

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. Cheers, Andreas Am Jul 18, 2012 um 10:37 AM schrieb Hans Hagen:
