R SIG Debian - Aug 2022 - Font issue under X11() (Ubuntu 20.04)

Hi all,

Using R under (X)ubuntu 20.04 here. I just noticed that the equal symbol (and
other symbols like <>) are hanging kinda low under X11(). For example, if
I run this code:

plot(NA, xlim=c(0,2), ylim=c(0,2))
text(1,1,"P = 0.01", cex=2)
abline(h=1)

then the = symbol is completely below the horizontal line, which looks a bit
off. I can fix this with X11.options(family="...") by using a
different font, but I am just wondering if there is something misconfigued on my
system or if other people are seeing the same thing.

Running R with 'FC_DEBUG=1 R' shows that

family: "Nimbus Sans"(w)

is apparently used as the default.

Best,
Wolfgang

Looks to be the same for me under 22.04, but I am not sure what if anything I
can do for you here.  The package builds do nothing special with respect to
font configuration, setup, or load. "It's just R and x11."

Maybe a private email to Paul Murrell is the best way forward as this is
likely deep inside R ...
