The symbols in the file symb-imp-mis.mkiv are loaded by default because context uses
them for the itemise environment but a few of them have to be enabled before you can
use them and even then you need a font which contains them, e.g. DejaVu.

%%%% begin example
\setupbodyfont[dejavu]

\setupsymbolset[text]

\starttext

\starttabulate[|l|c|]
\NC \bf Name      \NC \bf Symbol              \NC\NR
\TB
\NC bullet        \NC \symbol [bullet]        \NC\NR
\NC dash          \NC \symbol [dash]          \NC\NR
\NC star          \NC \symbol [star]          \NC\NR
\NC triangle      \NC \symbol [triangle]      \NC\NR
\NC circle        \NC \symbol [circle]        \NC\NR
\NC square        \NC \symbol [square]        \NC\NR
\NC diamond       \NC \symbol [diamond]       \NC\NR
\TB
\NC blacktriangle \NC \symbol [blacktriangle] \NC\NR
\NC blacksquare   \NC \symbol [blacksquare]   \NC\NR
\NC blackdiamond  \NC \symbol [blackdiamond]  \NC\NR

\NC 2             \NC \symbol [2]             \NC\NR
\NC 3             \NC \symbol [3]             \NC\NR
\NC 4             \NC \symbol [4]             \NC\NR

\NC 6             \NC \symbol [6]             \NC\NR
\NC 7             \NC \symbol [7]             \NC\NR
\NC 8             \NC \symbol [8]             \NC\NR
\stoptabulate

\stoptext
%%%% end example

When you need characters like the mentioned losenge you should better look for a font
which contains it and create a new typeface for it or set a fallback font which add the
characters to the main font of your document.
