Re: plotting points formatted in utf8

I tried the following script on 5.4.3 and 5.5 (last modified 2022-01-29) on cygwin
also tried 5.2.8 on windows (I do not have version 5.2 on cygwin) with wxt terminal.

The results are the same. 
The screenshot the below was taken on 5.4.3.

Used script is

# begin
reset session
	set encoding utf8
	set terminal x11 1 nopersist enhanced
set sample 20
plot x w p pt  "◎", \
0.8 * x w p pt "0x9678" , \
0.6 * x w p pt "U+25CE"
 # end

For 5.2.8 on windows, I used the wxt terminal instead of the x11 terminal.
