Yes, but this only works for Type1 fonts, not for OpenType.
The example below is a literal copy from metapost manual (created by Taco).
You first search in the source for that glyph:
\definemathsymbol [bigotimes] [op] [ex] ["4E] % this equals 78 in
decimal notation
and then you need either name or number of glyph + name of font.
fontmapfile "=lm-math.map";
beginfig(1);
picture q;
path p;
interim ahlength := 12bp;
interim ahangle := 25;
q := glyph 78 of "lmex10" scaled .2;
% q := glyph "circlemultiplytext" of "lmex10" scaled .2;
% cheat by looking at lm-mathex.enc
for item within q:
p := pathpart item;
drawarrow p withcolor (.6,.9,.6)
withpen pencircle scaled 1.5;
for j=0 upto length p:
pickup pencircle scaled .7;
draw (point j of p -- precontrol j of p)
dashed evenly withcolor blue;
draw (point j of p -- postcontrol j of p)
dashed evenly withcolor blue;
pickup pencircle scaled 3;
draw precontrol j of p withcolor red;
draw postcontrol j of p withcolor red;
pickup pencircle scaled 2;
draw point j of p withcolor black;
endfor
endfor
endfig;
end.
