Hello all,

I always come up with vague question, so here is another one. 

I use a virtual font to re-encode a real font and it seems that font expansion 
is not used anymore. Is this a well known thing? Both fonts (the real font and 
the virtual font) have the same parameters stretch/shrink/step, auto_expand and 
expansion_factor for each glyph. 

(If no, then I will try to sort out and try to make a small test case)


(BTW: LuaTeX 1.0.4 and 0.79.1)
