In Debian's native gnuplot 5.2pl6 I get:

  gnuplot> show encoding
          nominal character encoding is default
          however LC_CTYPE in current locale is C.UTF-8

while in 5.4rc2 I get:

  gnuplot> show encoding
          nominal character encoding is utf8
          however LC_CTYPE in current locale is C.UTF-8

Setting encoding to "default" rather than "utf8" indeed fixes the problem
I had in the x11 terminal on 5.4rc2.

Ah, interesting: if I start gnuplot 5.4rc2 with LC_CTYPE set to C, I get
the same as you:

  gnuplot> show encoding
          nominal character encoding is default
          however LC_CTYPE in current locale is C

So, somehow, Debian's native gnuplot sets encoding to default even in
the C.UTF-8 locale, while 5.4rc2 only does that in the C locale.

Thanks for the help; this provides me with sufficient ways to circumvent
the problem.
