[luatex] LuaLaTeX + TikZ + dvisvgm font problem (Alexander,J)

[Alexander,J]

I should also have noted that the font problem only appears when --output-format=dvi is specified.  When the output is specified as PDF, the font selection commands work as they should.

Is this because fontspec doesn’t support output to DVI? I searched the fontspec documentation but couldn’t find anything.

> 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.
