Mylke,

Have you tried using the "\u###" tool, where ### is the Unicode number? For
example,

plot(c(1:10) ~ c(1:10), main="\u2202 foobie bletch \u0192")

produces a del character and italics function "f". You may wish to use
different Unicode characters, but these were the first character codes I
found.

To look up the Unicode numbers, I personally like to use the "insert special
characters" tool in Pages, which may be found at:

Edit -> Special characters

Alternatively, a web search for "Unicode characters" should give you several
sites to find this information at as well.

Hope this helps!
