Thanks. I think this finishes to explain what is happening.

In the big blob of data that embeds the emmentaler-11 font in the PS 
file, there is the string "2.23.7" somewhere, next to licensing info. 
Apparently, Fontconfig is preferring that font file from 2.23.7 under 
~/.local for glyphs that exist in it (numbers), but it falls back to the 
good one for glyphs that 2.23.7 doesn't contain, the accidentals. This 
results in a mix of font files, as we have seen in the stencil 
expression dumps you posted.

Then, the two font files, one from 2.23.7 and the good one from 2.23.10, 
are conflicting under the name "Emmentaler 11" for being embedded in the 
PS file. Depending on how the input file is made exactly, either one 
could get to it first. In this case, the 2.23.7 one gets embedded. The 
2.23.10 one doesn't because LilyPond apparently thinks it has already 
embedded that font. Actually, scm/framework-ps.scm line 256 tries to 
display a warning in this case, so we need to investigate why this 
warning isn't triggering.

Then the accidental glyphs aren't found by Ghostscript, leading to these 
squares.

So we need to figure out a solution for this font finding issue.
