[Gnuplot-info] displaying unicode/utf-8 characters

[Kevin K. <kk...@gm...>]

It is not completely clear to me how to use utf-8 symbols in my plots.
Through web searching I have determined the following:



1. I need to use an enhanced output format

2. I need to set character encoding to utf-8

3. I need to ensure the gnuplot command file itself is in utf-8



Given the above, here are the commands I am using for 1. and 2.:



set term png size 1600x1200 enhanced

set encoding utf-8



Here is the linux command I use for part 3:



iconv -f iso-8859-1 -t utf-8 -o <utf-8_file> <original_file>



I want to use greek characters in my xlabels.  Every example I find online
says to simply copy the greek character from somewhere else and directly
paste it into my gnuplot command file.

The problem I have is that the text editor I am using (Nedit) does not seem
to support these symbols and they appear as '?' when I try to paste them
from somewhere else.  This then

produces a '?' character in my plot.



Is there a way to specify the character using its hex code?  For example,
the lowercase Greek 'mu' has code 0x3BC.  I tried using all of the
following to reference this character:



03BC

"03BC"

"U+03BC"

"\UO3BC"

"\u03BC"


But all of these strings end up being interpreted literally and do not
produce a 'mu' character.  Is there some specific syntax I can use to
display a unicode character using its hex code?
