[luatex] LuaLaTeX + TikZ + dvisvgm font problem

[Alexander,J]

Yes — I should have specified my system configuration more clearly.  I’m running lualatex using the 2022 texlive installation on Mac OS X Ventura 13.6.3, and was attempting to use the system font Optima, which comes pre-installed with OS X.
