Most likely your gnuplot session is operating with encoding utf8,
but your x11 terminal font handling is not set up to handle it.
It is possible to set it up, but it's a horrible pain and depends on exactly
what fonts you have available.   Either switch to
     set encoding iso_8859_15    (probably)
or switch to another terminal that has kept up with the modern world
and knows how to handle utf8.  I long ago switched to from x11 to qt
for daily use, but wxt or even sixel might fit your environment better.

If you stick with x11  and iso_8859_15, remember to switch the
encoding back to utf8 for output to pdf or TeX.
