Thanks Gabriel. Sounds like both you and Brian can build the branch on
Mac. Just need to check that Windows builds before I commit to r-devel.

I do my devel/patch work on Mac so I can take a shot at testing your
branch in the next couple days.

Hi
I have created an R branch that contains a potential fix ...
https://svn.r-project.org/R/branches/R-symfam/
This allows, for example, ...
cairo_pdf(symbolfamily="OpenSymbol")
... to specify that the OpenSymbol family should be used as the
"symbol"
font (e.g., for "plotmath") in R.
This is just a separate branch for now because, while I have tested it
under Unbuntu 18.04 and Fedora 31, I cannot even build R for Windows
(right now) or Mac (ever) and I do not want to drop a bomb on
R-devel at
this stage of the release process for R 4.0.0.
The attached file contains at least an outline of steps required to
do a
minimal test if anyone wants to try the fix on Linux.
cc'ing Simon and Jeroen in case they are able to help with checking
that
this builds and works on Mac and/or Windows.
NOTEs:
- 'symbolfamily' can only be specified when a graphics device is
opened,
and it is then fixed for that device.
- on Windows, for cairo-based devices, the "symbol" font is still
hard-coded as "Standard Symbols L"
