Re: [dev-context] context reference

Hello Taco,
I would like to keep a working copy of the context-reference (http://foundry.supelec.fr/svn/contextman/context-reference) on my hard-drive and use this as my first reference for my context questions, in order to send you suggestions for improvements whenever I notice some.
But of course, first it should compile. Today there are some errors, the first one is this one:
! Undefined control sequence. <recently read> \blacktriangleleft
Oh, right (I knew this). Hans, any idea where it went? Best wishes, taco

It comes from the old "ma" encoding and I guess it has never been added to char-def.lua in the first place. (The symbols from mi, sy, ... have been checked more carefully than those from ma, mb, ...) Is this U+25C0 or U+25C2 (or maybe even U+25C4)? Mojca
I have just found an interesting source that could be used to check
for any missing characters:

math-vfu.lua says 25C0, but this document (http://www.xmlgrrl.com/publications/DSDTD/apd.html) would rather suggest 25C2: In char-def.lua: the following two lines need to be added to either [0x25C0]={ or [0x25C2]={ inside char-def.lua: mathclass="rel", mathname="blacktriangleleft", and if they are added to 25C2 then also the entry in math-vfu.lua should be changed (and all other characters as well). How do the characters in Cambria math look like? Which one comes closer? Mojca

The actual usage in the manual is as a flipped version of 0x2023 (triangular bullet) but that doesn't exist at all. Which Unicode character is best for the math relation, I have no idea (but see below).

There are no black triangles in Cambria Math *at all*, it seems. Best wishes, Taco

Oh. Then I got it completely wrong in my earlier mail; since U+2023 has a reference to U+25B8, the smaller one, this would rather plead for using U+25C2, its sibling, as \blacktriangleleft.

Indeed, the U+25XX row is entitled “Geometric Shapes” and is not related to math. Arthur

The criterion would rather be: how is it used in ConTeXt? And from what I read in symb-mis.tex, it seems that it is used as a "rewind" character, hence a rather big triangle, more like U+2520 than U+2522. Arthur
