You are after what Adobe calls: udblacute; 0171. It is recognized in
the list of adobe glyphs:
> str(tools::Adobe_glyphs[371, ])
'data.frame': 1 obs. of 2 variables:
$ adobe : chr "udblacute"
$ unicode: chr "0171"
Consulted the help pages
points {graphics}
postscript {grDevices}
pdf {grDevices}
charsets {tools}
postscriptFonts {grDevices}
I have tried a variety of the pdfFonts installed on my Mac without
success. You can perhaps make a list of fonts on your machines with
names(pdfFonts()). Perhaps the range of fonts and the glyphs they
contain is different on your machines. I get consistently warning
messages saying there is a conversion failure:
> pdf("trial.pdf", family="Helvetica")
# also tried with font="Helvetica" but I think that is erroneous
> plot(1,type="n")
> text(1,1,"print \U0170\U0171")
Warning messages:
1: In text.default(1, 1, "print ??") :
conversion failure on 'print ??' in 'mbcsToSbcs': dot substituted
for <c5>
2: In text.default(1, 1, "print ??") :

And this is despite my system saying the \U0170 and \U0171 are present
in the Helvetica font. Also tried family=URWHelvetica and
family=NimbusSanand and a bunch of others without success, but my last
best hope after reading the material in help(postscript) in the
"Families" section had been NimbusSan. There is also information on
that page regarding encodings that appears to be very machine specific.
