I sent this privately to ivo welch yesterday, and he thinks it might
be useful to someone else as well. Since I'm on a Mac the screen
device is quartz():

# and then File/Save As/

yes, I got the same thing.
When I plot to the Mac default screen device (which only does "Save
as.." to pdf files) I get the desired glyph. Saving it produces the
desired file. If you need to save files programatically, there might
be work-arounds using the screen device as an intermediate.
You could also look up this obscure reference:
http://finzi.psych.upenn.edu/Rhelp10/2009-August/209605.html
The author (me) says that he found out that UTF-8 is not an
acceptable encoding and that others are needed for ps devices (and
perhaps this applies to pdf as well, but he is unsure) and can be
found in your grDevices folder. I wish I could tell you which
combination of encoding with which font can get you what you want
but that is beyond my ken.

Dear R experts---is it possible to plot the \ell symbol in R
under the
pdf device? the following did not work:
pdf(file="ell.pdf");
plot( c(0,1), c(0,1) );
text( 0.5, 0.5, "\u2113" )
dev.off()
my guess is that this cannot be done, but I thought I would ask.
(On a Mac:)
After 7 warning messages I got an ellipsis ("...") printed at the
desired
location. Interestingly I think the error message might have
properly
printed the desired glyph (assuming you wanted a cursive lower
case "l":
Warning messages:
1: In text.default(0.5, 0.5, "ℓ") :
conversion failure on 'ℓ' in 'mbcsToSbcs': dot substituted for
<e2>
I also looked in the Hershey fonts without recognition (but could
have
missed one). One the Mac there is an option among the Zapfino
family but I
suspect that is of little use to you.
