Hi all,
I have found after upgrading to R 4.0.0 (among other upgrades so this may
not be the cause) that the degree symbol doesn't work correctly on Ubuntu
18.04. Googling brought me to this thread that appears related.
I tried running:
cairo_pdf()
plot.new(); text(0.5,0.5, bquote(120*degree*N), cex=5)
dev.off()
and the ubuntu plot has the degree symbol vertically in the center of the
line. The Windows one correctly shows as superscript.
Anyone else see this behaviour?
Cheers,
Kenny

Hi Paul,
Hi Gabriel,
Thanks a lot for the testing.
The various font family settings seem to work too, from what I can
tell. Both font families you suggested, however, Helvetica and Apple
Symbols (the s is important) have significantly incomplete coverage
with PUA on.
That is to be expected, the AMS symbol dump in PUA space was a quick
hack to make pre-unicode symbols available in an unicode world, pending
their normalisation.
That standardisation is long past (IIRC it occured by unicode 3.2
released in March 2002), so no newly created/updated font family is
going to place those symbols in PUA anymore.
Now adding the AMS symbols to new fonts has been slow, due to the large
amount of software hardcoding Symbol (and equivallent) and masking the
actual glyph userbase to font makers. It will accelerate with more apps
expecting plain unicode by default.
Thanks for the testing!
Regards,
