听说 terminator 这个 Linux 终端不错，就安装了一个。然后习惯性地输入命令： terminator -h

结果显示：

Traceback (most recent call last):

    file.write(self.format_help().encode(encoding, "replace"))
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position 118: ordinal not in range(128)

貌似是字符集问题，但对 python 不熟悉，请教高手，该怎么处理才能让它显示帮助信息？
