By default, Gnuplot's X11 terminal does not support UTF-8 characters when displaying text labels or setting plot titles. To enable support for UTF-8, add the lines below to your ~/.Xdefaults.

! gnuplot settings
gnuplot*font: mbfont:-misc-fixed-medium-r-normal----100-100---iso10646-
gnuplot*encoding: utf-8

To enable these settings, type the following command at the shell prompt.

xrdb -merge .Xdefaults

To avoid having to type this command repeatedly, the command may be placed in your shell script resource file, ~/.profile for example.
