Specify encoding='utf-8' in Path.open() calls in personalize_file()

[Akshaya Annavajhala]

🐛 Describe the bug

by default, the open() command in text mode ('t') will use the platform encoding, which on windows happens to not be utf-8. In your case as the content is known to be utf-8, a simple fix would be to specify the encoding= kwarg on open()
