求助， Linux 下的终端 terminator 字符集问题

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 "/usr/bin/terminator", line 69, in <module>
    OPTIONS = terminatorlib.optionparse.parse_options()
  File "/usr/share/terminator/terminatorlib/optionparse.py", line 110, in parse_options
    (options, args) = parser.parse_args()
  File "/usr/lib/python2.7/optparse.py", line 1399, in parse_args
    stop = self._process_args(largs, rargs, values)
  File "/usr/lib/python2.7/optparse.py", line 1443, in _process_args
    self._process_short_opts(rargs, values)
  File "/usr/lib/python2.7/optparse.py", line 1550, in _process_short_opts
    option.process(opt, value, values, self)
  File "/usr/lib/python2.7/optparse.py", line 788, in process
    self.action, self.dest, opt, value, values, parser)
  File "/usr/lib/python2.7/optparse.py", line 810, in take_action
    parser.print_help()
  File "/usr/lib/python2.7/optparse.py", line 1669, in print_help
    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？
