Ah, I'm sorry for poor explanation.

What I'm trying to do is: a patch for FreeType2 library to change
the default FT_Face->family_name when a TrueType/OpenType font
without ASCII family name is given. My concern was that such
change may have any bad impact to fontconfig.

But, as Behdad and you told, it seems that the names handled by
fontconfig are copied from "name" table and not a copy of
FT_Face->family_name. So, I understand as there is no impact at all. 
It is good news!

I have to check other applications which write FT_Face->family_name
as a persistent font identifier into their output files.
