But the symbols wouldn't even be there if you used a different editor in the first place :)
Here's the problem:
Random symbols. We know that.
How it started:
For me, Notepad was blocked accidentally. I told my parents and they did nothing. I already had the code on Google drive and downloaded it as a .txt. I changed the type to .cs, created a .zip folder for it and put it into Blockland. Then this happened.
Hope this explains somewhat of how it happened.
