Yes, for me too.
X11() *is* by default the "X11cairo" device and that works, the
same as the "Cairo PDF" device that Jeff mentioned above.
Indeed,
cairo_pdf("utf8-ex.pdf") # works nicely
whereas pdf("utf8-ex.pdf") does not {for me, with default font
families etc}, but rather shows the "..." instead.
*and* gives warnings during the plot
conversion failure on 'EVENT ? 30 sec' in 'mbcsToSbcs': dot substituted for <e2>
conversion failure on 'EVENT ? 30 sec' in 'mbcsToSbcs': dot substituted for <89>
conversion failure on 'EVENT ? 30 sec' in 'mbcsToSbcs': dot substituted for <a5>
BTW, a simple one liner for testing is
plot(1, type="n", axes=FALSE, main = "EVENT ? 30 sec")
Note that help(pdf) contains

cairo_pdf and (on macOS only) quartz for other devices that

Hello,
I can confrim this behavior with cairo_pdf(), it works as expected
printing "EVENT ? 30 sec".
But with pdf() I get an equal sign "EVENT = 30 sec" and no errors.
Full code:
cairo_pdf("~/Temp/cairo_pdf_utf8-ex.pdf") # works
plot(1,1, pch = "")
text(1, 1, "EVENT ? 30 sec")
dev.off()
# null device
# 1
pdf("~/Temp/pdf_utf8-ex.pdf") # prints "=", no warnings
plot(1,1, pch = "")
text(1, 1, "EVENT ? 30 sec")
dev.off()
# null device
# 1
sessionInfo()
# R version 4.2.1 (2022-06-23 ucrt)

#

#
Also, nice trick to print the text as plot title, I will remember that
one-liner.
Hope this helps,
