All symbol fonts are tricky with mkiv because luatex moves them
to the private slots, you can see this on the terminal when you
load the font for the first time.

I found no system how the original position in the font and
the assigned position is related, maybe Taco knows a answer.

With the message above from the terminal you can now load
the symbols with \char"F00xx but mkiv provides also a mechanism
to access a symbol by the glyphname with \fontchar{T_e_X}.

I attached a modified version of the cow symbol where i used
the glyph names for each symbol but what we need are different
files for the symbols in mkii and mkiv. Hans, can you modify
the \usesymbols command to behave like \usetypescriptfile which
looks first for a mkii/mkiv file and then for a tex file?

You can use the text fonts with \setupbodyfont[cow].
