Hi, are the delimiters \lgroup and \rgroup supported in MkIV? This
\starttext $$\bigg\lgroup\dots\bigg\rgroup$$ \stoptext
is ok in MkII (ConTeXt ver: 2011.01.06) but when compiled with MkIV (ConTeXt ver: 2010.07.30 11:35 and ver: 2010.07.30 11:35) the delimiters are not shown. (By the way, the same holds true for \rmoustache and \lmoustache.)
Am I missing something?
No. The math mappings of virtual fonts are incomplete. The symbols should work correctly with unicode math fonts like cambria, asana, and xits. But, it appears that lgroup and rgroup are missing from xits (Khaled?)
There are, but context is looking for the wring character; it is looking for U+3014 (which I think is a CJK bracket and does not look like \lgroup either) while it should be looking for U+27EE (whose Unicode annotation precisely says "lgroup"):
Hmm ... 27EE does not exist: http://unicode.org/charts/PDF/U32-27C0.pdf I believe that I used 3014 based on http://www-sop.inria.fr/apics/tralics/doc-l.html#cmd-lgroup
What source do you use for the symbols?
I opened Gnome's Character Map and searched for lgroup :) (but I've seen it before, so I know it exists, I just don't recall the code point). Now that you asked, I checked Unicode website and they have "Miscellaneous Mathematical Symbols-A":
That was the same range that I had looked at, but somehow that pdf did not have 27EC-27EF. Neither does char-def.lua. So, I guess that these are newer additions. I will add them to char-def.lua and correct the mappings for lgroup and rgroup. Aditya
