Checks if this application runs with a correct locale (i.e. supports UTF-8 encoding) and attempt to fix
    if this is not the case.

    This is to prevent UnicodeEncodeError with unicode paths when using standard library I/O operation
    methods (e.g. os.stat() or os.path.*) which rely on the system or user locale.
