[R] \ell symbol (log-likelihood)

[ivo welch]

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.
