Answer 6

Thanks @M N
But why that happened!? How spaces can be invalid characters!? It's because of Keyboard or something

Answer 7

Can you write some lines of code for me so I can cut them and test the spaces? I want to check where this happens.

Answer 10

No the bug comes from your device. What keyboard are you using? Maybe use another language setting or another keyboard.

Answer 11

I tested around a bit and not all of your spaces are encoded wrong. Hard to tell what's the exact problem.
But we know the reason. Have you tried another keyboard?

Answer 12

I checked the code and detected that spaces at the start of lines are invalid chars, so removed them and using tab button of the code playground added them again.
the code works now:

Answer 13

only the spaces at the begining of lines was invalid, other spaces were valid
i think that you use tab key of your keyboard at the start of lines and it has problem, try a very simple code with a line, and test with the tab key of your keyboard and tab key of code playground
