(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.
