UnicodeDecodeError

[logica-umeno]

What were you trying to do?

Running code with Japanese comments in PygameZero mode

What steps did you take to trigger the issue?

For Japanese children, understanding source code in English is very difficult. Therefore, I teach them to write explanations of the source code in Japanese.

• I chose PygameZero Mode.

• I wrote the following code

# エイリアンを作成する
alien = Actor('alien')

• I pressed the Play button.

What did you expect to happen?

UnicodeDecodeError occurred.

What actually happened?

Other Info

It seems that Python is mistakenly recognizing the code as being written in cp932.
Therefore, if you write the following at the beginning of the source code, it will work correctly.

# coding: cp932

However, if the checking function is used on code with cp932 specified as the character encoding, MU-Editor crashes.

    line = line.decode(encoding)
UnicodeDecodeError: 'cp932' codec can't decode byte 0x88 in position 24: illegal multibyte sequence

I hope that Japanese comments can be written in PygameZero, and that the checking function works correctly.
