On both windows and Linux the following fails on Python 2.7: s = '\\Upsilon' unicode(s,"unicode_escape") UnicodeDecodeError: 'unicodeescape' codec can't decode bytes in position 0-7: end of string in escape sequence BTW, the six.py package uses this call. If this call doesn't work, six is broken. |

This is not a bug, \U should be followed by 8 hex digits and it indicates a Unicode codepoint:
>>> '\\u0065'.decode('unicode_escape')
u'e'
>>> '\\U00000065'.decode('unicode_escape')
u'e'
>>> '\\Upsilon'.decode('unicode_escape')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'unicodeescape' codec can't decode bytes in position 0-7: end of string in escape sequence
>>> u'\Upsilon'
File "<stdin>", line 1
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 0-7: end of string in escape sequence
>>> u'\U00000065'
u'e'

Thanks for your quick reply. If this is not a bug, why does six define six.u as unicode(s,"unicode_escape") for *all* u constants?? |

Because as Ezio demonstrated, it produces the same result as using the 'u' prefix on the same string. |
