The value of :font can be a fontset, so you don't need to use the (obsolete and not really supported) :fontset attribute. The doc string of set-face-attribute documents :font, not :fontset, and that is not an accident. If you replace all instances of :fontset above with :font, fac-font will not return nil. This is not a bug.

Actually, if you pass the fontset through the `:= font' attribute, only the ASCII font from the fontset is used. This applies to both `set-face-attribute' and `f= ace-remap-add-relative'. AFAIU, I think when it comes to the face attribute= s, the fontset feature is more like a way to set different font for diferen= t character sets, making it able to "display the whole range of characters that Emacs supports" f= or a given face, since setting the `:family' attribute or assigning a singl= e font to `:font' would suffice for setting font only for ASCII characters.= So the case is, either the `:font' attribute needs to consider the full fontset, or the whole fontset feature is, as yo= u said, "obsolete".

Don't use :fontset as a face attribute; use :font instead.  The value<= br> of :font can be a fontset, so you don't need to use the (obsolete and
not really supported) :fontset attribute.  The doc string of
set-face-attribute documents :font, not :fontset, and that is not an
accident.

If you replace all instances of :fontset above with :font, fac-font
will not return nil.

This is not a bug.

Yes, because the faces that are exposed to Lisp are always the faces used for characters supported by the "ASCII font" of a face. For other characters, Emacs creates internally a separate face, which is not exposed to Lisp, and determines its font from the fontset in effect, merging the other relevant face attributes to produce a face as similar as possible to the one used for characters covered by the "ASCII font". > This applies to both `set-face-attribute' and `face-remap-add-relative'.

So the case is, either the `:font' attribute needs to consider the > full fontset, or the whole fontset feature is, as you said, "obsolete". Then please explain in more detail what you are trying to achieve, and why. The code snippet you presented makes it hard to guess, since it defines a face with a special fontset, and then remaps the 'default' face to that face. Why would you need to do that, instead of simply customizing the default-fontset or setting the :fontset attribute of the 'default' face? The technical reason for what you see is that face-remapping creates an anonymous face with the specified attributes, and Emacs doesn't support the :fontset attribute for anonymous faces. But since I don't really understand why you use face-remap-add-relative, I cannot tell whether this is a problem or how to solve it for your needs.
