I use Arduino IDE v1.8.10 and today I’ve faced a problem. All the projects I’ve coded are shown in some weird characters (see attachment). In fact, the code itself is not damaged, I’m sure because I’ve opened the same projects by Notepad and all the codes are there.
More, when I copy the code and paste it into Word, it’s all O.K.
So, why can’t I see the code properly in Arduino IDE? Any solution?
Thanks in advance for your contribution.
