Hi Rip, the problem is that while Lilypond will embed the glyphs into the eps it will reference them with a simple sequence. This cannot really be interpreted as text (the first glyph will be referenced as "1", which is the "Start of Heading" character). So either this will in fact fail to extract this glyph at all, or it will turn it into a string containing a simple CC, which is then of course not displayed.
If you include enough glyphs you will get normal chars (try for example this
#(define glyph-list
(lset-difference
equal?
(ly:otf-glyph-list (ly:system-font-load "emmentaler-20"))
'(".notdef" "backslash")))
\markuplist #(map (lambda (x) (markup #:musicglyph x))
glyph-list)
), but these will probably simply be rendered with any font available on the
system instead of the actual glyphs (unless AI does a thing where it tries to
reconstruct the font from the embedded glyphs, which would defintely require
more effort than simply importing the glyphs and replacing the font references
with references to these glyphs, which AI does not appear to be doing in this
case.
But then this is not really an issue of Lilypond but of how AI imports file
with such glyphsets. Also going into AI via eps seems a bit counterintuitive
for me. After all PS is not particularly good at storing data in a machine
readable way, so AI will have to try to interpret what it sees. Instead, why
not go for SVG-Output, which is a format that is intended to store data in a
machine readable way and simply has to be parsed by AI? In fact the SVG output
will not store these glyphs as font references, but will insert paths, getting
rid of all dependencies to specfic font files (although I remember that with
much earlier versions like I think 2.18 this was not the case).
Cheers,
Valentin
