special characters

Text specifications may include embedded special characters. These correspond to the PostScript Symbol font and thus may be used in PostScript mode only. The PostScript special characters feature was written by Marvin Newhouse.

If doing PNG, GIF or X11, you can render any of the characters found in the ASCII range 128-255, by embedding the desired ascii value within the text item.

EXAMPLE

Title: Cities having average temperature \\(<= 20 degrees C
