Hi,
how can I check (in Lua or ConTeXt) if a symbol or color is defined?
\doifdefined is just for macros, isn’t it?
And how can I check if the current font has a glyph?
i suppose you grepped a bit
\doifelsesymboldefined
\doifelsecolor
\doifelsefontchar
and friends ....
also listed in setup-en.pdf
Oops, thanks!
