Having delved into the depths of the way fonts are created and work in
LilyPond, I agree that this is the most precise correction here. I guess
the only question is should it be "emmentaler-xx" (which is the font file
name) or "Emmentaler-xx" (which is the internal font name). Which is the
correct reference? It's a small detail, but perhaps it's best to get it
right and be done with it.

The three encodings are basically as follows:
- fetaText: all alpha-numeric glyphs (i.e., /space, 0-9, and the letters f,
m, p, r, s, z).
- fetaBraces: all grand-staff brace glyphs (all of which are found in the
font "emmentaler-brace")
- fetaMusic: every other glyph, including those found in the "parmesan"
sub-set of glyphs.

I suppose this would be good information to have documented somewhere.

Also, I wonder if a new entry should be in the "Entire Document Fonts"
sub-section to describe the usage of set-global fonts? I can't say it
should completely replace the make-pango-font-tree example, but there isn't
an entry for set-global-fonts anywhere at the moment.

Agreed.

On a side, but related, note, the whole business with using the names
"feta" and "emmentaler" interchangeably is a bit confusing all throughout
the code. For example, the use of 'feta as the font-family symbol for the
music font. Why not just call it 'music? The three main encodings could
then be 'musicText, 'musicBraces, and 'musicSymbol (I've not bought-off
that last one). Perhaps it's just me coming from the world were other music
fonts are now available. After all, we use the more generic terms 'roman,
'sans, 'typewriter for the main text font-families.

That's all for now.

Best,
Abraham

Hi Carl, are you sure?
The context of my report was:

   Issue 4966

   Distinguish between Emmentaler
   the 'font' and Feta/Parmesan
   glyphs that make up the
   Emmentaler font family.


That is quite imprecise wording: Feta and Parmesan are subsets of the 
Emmentaler font, not individual glyphs.
Whether ‘font name’ in that NR table is also imprecise is a matter of 
little importance IMO – it’s the least confusing choice of words and I 
don’t see any need to change it.


Best, Simon

In this context, I guess that the proper word is 'subfont' rather than
'glyph'.  The emmentaler font is made up of several subfonts, according to
the files in the out/mf directory.  In the case of emmentaler-11 (which is
the font), the subfonts include
feta11
feta-noteheads11
feta-flags11
parmesan11
parmesan-noteheads11
feta-alphabet11 

Each of these subfonts is a collection of glyphs.  And the glyphs have
individual names.

If I were to try to fix the problem you have identified, I would probably
change the contents of the first column from 'fetaxx' to 'emmentaler-xx'.
I believe that when one sets the font-size in general, it applies to
Emmentaler, not to Feta.  The only place I have found in the documentation
that uses anything other than the whole font is in NR 1.8.3, where some
font-encodings are used.  But I cannot find any documentation that
describes which glyphs are in which encodings, so I don't know how to use
this in general.

So, in looking at all of this, my recommendation is not to change the
heading of the table, but to change the contents of the first column.

Thanks,

Carl

Not in my opinion.  The font is feta11 (the font family is feta).  The
staff height is 11.22 pt.  The staff height is 3.9 mm.

Not in my opinion.  The font is feta11 (the font family is feta).  The
staff height is 11.22 pt.  The staff height is 3.9 mm.
