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
