UTF-8 error?

[detruuteron]

A friend of mine got this error on his game and we don't know what to do.

I'm sorry, but an uncaught exception occurred.

While parsing C:\Users\clau\Downloads\A world truly laughable/game/script.rpy.
UnicodeDecodeError: 'utf8' codec can't decode byte 0x97 in position 1168: invalid start byte

Most probably the script.rpy files is stored in some encoding other thana utf-8. Make sure that whatever editor you are using to save/make changes to the script is saving the file in utf-8
