我在使用 eclipse、pydev、nose 测试运行器和记录 unicode 文本时遇到了一个奇怪的问题。我不知道这是否只发生在我的配置和安装的版本中。所以，如果你们中的一些人可以尝试重现这个问题，并告诉我你是否有同样的问题，这对我很有帮助。我希望在下面的评论中复制所需的所有信息。请注意使用鼻子测试运行器，而不是禁用日志捕获。

import unittest
import logging

class WeirdUnicodeTestProblem(unittest.TestCase):
    """
    Weird Exception is raised in
        xmlrpclib (!)
    Fault: <Fault 0: 'Failed to read XML-RPC request:
        Invalid byte 1 of 1-byte UTF-8 sequence.'>
    Occurs when this is true:
     - nose test runner with log capturing on (=default)
     - eclipse + pydev
     - log some unicode text containing non standard ascii characters
     - raise any exception after logging 
    It does NOT occur when using nosetests on the commandline.
    """
    def test_problem(self):
        """
        This is how the problem can be reproduced
        """
        logger = logging.getLogger('bla')
        logger.debug(u'internation\xe4l')
        self.assertEqual(1, 2) # any exception raised will do here

    #def test_OK(self):
    #    """
    #    This is how the problem does not occur
    #    """
    #    logger = logging.getLogger('bla')
    #    logger.debug(u'good old 7bit')
    #    self.assertEqual(1, 2) # any exception raised will do here

这是回溯：

Traceback (most recent call last):
  File "/Applications/eclipse_4.2.1/plugins/org.python.pydev_2.7.3.2013031601/pysrc/pydev_runfiles_xml_rpc.py", line 131, in run
    self.server.notifyCommands(commands)

    raise Fault(**self._stack[0])
Fault: <Fault 0: 'Failed to read XML-RPC request: Invalid byte 1 of 1-byte UTF-8 sequence.'>

还有一件事更奇怪：如果我在第 131 行的 pydev_runfiles_xml_rpc.py 设置断点并尝试调试它，断点甚至没有命中，但代码运行干净（如预期的那样引发 AssertionError）。

请注意，这确实是 PyDev 端通信中的一个问题（因此，尽管它显示了该错误，但它不应该真的使您的测试失败）。

我正在为 PyDev 建立一个新的跟踪器，作为http://igg.me/at/liclipse的一部分，所以请在跟踪器启动后将其报告为跟踪器中的错误。
