I think this is entirely up the the local configuration of your
desktop environment.

The "set/show encoding" command in gnuplot controls how gnuplot
handles the output.  It does not affect input.

That is very strange.  I would have thought that any input method
that worked for your terminal shell prompt would also work for an
instance of gnuplot running in that same terminal.

For me the key sequence <ctrl+shift+U>29b5 works either at the
shell prompt or inside gnuplot.  However in general if I want to enter
some relatively obscure character I use the KDE kcharselect tool to
look up the UTF-8 encoding value.  At that point it would be possible
to type <ctrl+shift+U>XXXX, but also at that point the symbol itself
is selectable in the kcharselect window.  So what I have done in the
past is double-click on the symbol in kcharselect and then paste
it into the shell or gnuplot prompt. 

Characters that I use frequently (e.g. Å µ °) also have pre-defined
dead-key or AltGr sequences for terminal entry.  You can define or
select these in various places including the KDE widget
"Input devices -> Keyboard settings".
