如何解决此错误消息，该错误是什么意思？

Question

我正在使用Twitter API流推文，并且不断收到此类错误。我该如何解决它们？某些推文成功流式传输，但是大多数时候尝试流式传输时出现这些错误。

许多错误中的一些（我得到的所有错误都与这些错误类似）

    ('failed ondata', "'ascii' codec can't encode character u'\\u2026' in position 139: ordinal not in range(128)")
    ('failed ondata', "'ascii' codec can't encode characters in position 86-89: ordinal not in range(128)")
    ('failed ondata', "'ascii' codec can't encode character u'\\u2026' in position 139: ordinal not in range(128)")
    ('failed ondata', "'ascii' codec can't encode character u'\\u2026' in position 139: ordinal not in range(128)")
