I performed some tests with font=5 on both Linux and Windows using
source("font5.R"), which is shown below, and then calling the Font5Test()
function.
Consistent results were seen with devices X11, png, and jpeg under either
Linux (R 2.1.1) or Windows (R 2.2.0) in my locale. Oddly, both the pdf and
postscript devices create 2 pages of output with the first page the expected
table and a second unexpected page with only the "clubs suite" symbol (167)
in the middle of the plot. I'd call this a bug, but I guess I haven't read
all the documentation about this yet.
