Eu tenho um script Python criado no Python 3.5.4. O script está importando o nltk. Quando estou tentando executar o script de java usando o Jython 2.7.1, ele está me dando os seguintes erros.

Exception in thread "MainThread" java.lang.ExceptionInInitializerError

SyntaxError: Non-ASCII character in file 'D:\Python\Lib\sqlite3\__init__.py', but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

Além disso, quando verifiquei a codificação padrão do Python e Jython, o resultado foi utf-8 e ascii, respectivamente.
