Hello,

I was answering another question here when I might have found a bug, that is hard to describe, but relatively easy to reproduce...

I tested on 2 different linux machines with gnuplot-4.6.5 and gnuplot-5.0.1 and few terminals (qt, x11, png) the following commands (you'll need UTF-8 to see some of them):

gnuplot -p -e 'plot sin(x) w p pt "A";'
gnuplot -p -e 'plot sin(x) w p pt "щ";'
gnuplot -p -e 'plot sin(x) w p pt "猫";'

The 5.0.1 works fine (4.6.5 is not supposed to allow this pt, so no issues), drawing a sine wave with the glyph specified.

However, the one below (UNICODE CAT FACE, U+1F431) does not work, no matter what I tired:

gnuplot -p -e 'plot sin(x) w p pt "🐱";'

(I confirmed I can see the glyph e.g. when using 'title "🐱"', so it is not font issue)

Any ideas? How can that be worded better, assuming it is a bug?

Cheers,
Kalin.
