A file that I have read includes strings like this:
	"EVENT ? 30 sec"
When I include the string in a graphic using:
	mtext(STRING, ?)
it appears as:
	"EVENT ... 30 sec"

Is there a simple work-around (short of reformatting all the strings, then using plotmath)?

How about  just 'EVENT > 30 sec' or 'EVENT > 29 sec' ?

Hello,

I had no problems with


X11()
plot(1,1, pch = "")
text(1, 1, "EVENT ? 30 sec")
#dev.off()


Hope this helps,

Rui Barradas

Hallo Dennis

Is the STRING in R still containing **?** character?
Or it was converted during reading to R to ...?

What dput(STRING) result i?
 
Cheers
Petr

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

   See Also:

        pdfFonts, pdf.options, embedFonts, Devices, postscript.

        cairo_pdf and (on macOS only) quartz for other devices that
        can produce PDF.

        handling text in a non-Latin-1 encoding and embedding fonts can be

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()

#


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

Hope this helps,
