I'm trying to put as the title of a plot "P@10" using GnuPlot, using the Helvetica font.
What I did was this:
set encoding iso_8859_1
set title "P \100 10"
The \100 comes from the octal representation of the at symbol in unicode. The final plot, however, replaces the @ with a simple space. Other symbols work as expected.
I also tried the matlab script provided here, to look for the @ symbol in at least 4000 different codes, but I couldn't find it.
Is this possible, even with another font?
EDIT: I tried this on three different systems, Ubuntu AND Windows, to no avail..
EDIT2: Minimal working example:
set term postscript eps enhanced color
set encoding iso_8859_1
set title "Test \@ Test" -or- set title "Test \100 Test"
set out "example.eps"
plot sin(x)
My output doesn't have any @ sign in the title.
