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)?
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.
keep in mind that not all those black triangles in ams math ended up in
unicode
(future lm/gyre fonts might have some of these symbols)
