Hello,
I have a general question about the primitives \Uoverdelimiter,
\Uunderdelimiter, \Udelimiterover and \Udelimiterunder. ConTeXt seems to use the
two former in math-ini.lua:
local function mathtopdelimiter(class,family,slot)
return format('\\Uoverdelimiter "%X "%X ',0,family,slot) -- no class
end
local function mathbotdelimiter(class,family,slot)
return format('\\Uunderdelimiter "%X "%X ',0,family,slot) -- no class
end
where the slot argument is unused?!
The extra ",0" format argument was a bug that has since been corrected.
I also tried to play around with them in plain LuaTeX:
\input luaotfload.sty
\font\cambria={name:Cambria Math:script=math} at 11pt
\textfont0=\cambria
This definition is not complete. You also need:
\font\cambriax={name:Cambria Math:script=math} at 8pt
\scriptfont0=\cambriax
because "1D44E etc. are not available in cmr7.
Best wishes,
