fail to display block element correctly in terminal

Question

When I use plotext to plot graph in Linux terminial which is connected via ssh, I find that it fails to display block elements correctly.

Here is the command I use

python3 -c "import plotext as plt; y = plt.sin(); plt.scatter(y); plt.title('Scatter Plot'); plt.show()"

And the output is

Some of the block elements, for examples ▝,▖ are displayed as question mark.

Is there anything I can do to make it right? My terminal setting is TERM=xterm-256color

Update
