I tested a little bit. The gnuplot-console gives to me the 
hexadecimal-code of every non standard character. Some examples:

ä gives me \U+FFC3\U+FFA4 c3 a4 is the hex-code for U+00E4 (I have the ä 
on my Keybord)
⦵ gives me \U+FFE2\U+FFA6\U+FFB5 e2 a6 b5 is the hex-code for U+29B5

It is an on all Terminals (LXterminal, gnome-terminal, 
standard-KDE-terminal) the same, on Debian stable and testing with KDE. 
And all Terminals can display every unicode sign.

On Fedora 21 it works "normal", there I can use non standard characters 
inside the gnuplot-console.

Is there a config-file?
