Hi,

whenever LuaTeX loads a TTF font but only uses a single glyph, which happens to be the notdef glyph (GID=0), LuaTeX complains about

(type 2): there are no glyphs in the subset

Of course this isn't true, because the notdef *is* in the subset.

This happens because LuaTeX always includes the notdef glyph, so it is never counted. The problem can be fixed by explicitly testing for this case.

Do you have an example ?

Of course:

\starttext \font\test=logix.ttf\test \char"F0000 \stoptext

See https://github.com/u-fischer/luaotfload/issues/73 for some context.

ok, thank you. I will see it asap . -- luigi
