Special characters in R plots -


i have code in use

plot(1, 1, type="s", ylab="log ℓ")

that equivalent to

plot(1, 1, type="s", ylab="log \u2113")

produces nice slanted l representing likelihood in y-axis.

why capital script version of l (\u2112) gives me box in place of l?

i'm running r on mac.
