\ell in postscript enhanced

[<Giu...@ct...>]

Hi everybody,

I would like to use a calligraphic lower-case l (LaTeX: \ell) in a label 
using gnuplot (set terminal postscript enhanced).

It seems not listed among the available characters within the Symbol font.

What other relatively "standard" postscript font would you recommend me to 
use, hopefully containing also other relevant math characters?

Thank you in advance.

Giuseppe.
