1. similar errors when connecting 2018b to RPi 3 B+
2. and the error message can't show the correct "font"

[Scott Huang]

ok ~, i solved this by using Matlab customized image(MathWorks Raspbian image).

but official Raspbian still can't work with matlab...no answer yet...

I also have similar problems when trying to connect Raspberry Pi 3B+ with Matlab 2018a and it seems impossible to solve the problem, but when I used Matlab 2019 (the las version), it works well. So, I think it's a matlab version problem.
