I'm developing a custom JS component. When I test the component it works fine on Linux but when I test on Windows I get UnicodeDecodeError: 'charmap' codec can't decode byte'.., It happens when the bundle is being loaded.

The problem is that fixed by adding utf-8 encoding to loader.

./reactpy/web/utils.py#L31

    export_names, references = resolve_module_exports_from_source(
        file.read_text(encoding="utf-8"), exclude_default=is_re_export
    )
