No.  groff accesses Type 1 fonts always by glyph names.

No.  Internally, all input characters, regardless of the input
encoding, are converted to entities from the Groff Glyph List (GGL;
you can find the details in groff.texinfo).  afmtodit does the same on
the font side.  Consequently, they fit within groff.

Today you should use the Adobe Glyph List (AGL).  I suspect that the
values for Cyrillic glyphs are still identical to the #5013 report,
though.

It allows you to use \N'...' with a glyph index number to access
glyphs without a name; this can happen if afmtodit can't automatically
deduce a GGL compliant name, for example, if you have glyph variants
like `foo' and `foo.small' in the same file.
