UnicodeDecodeError exception is reported for encode operation on strings.
This issue does not surface for the same operation on unicode string (UnicodeEncodeError exception is correctly reported).
---- string:
>>> 'AB\xff'.encode('ascii')
Traceback (most recent call last):
File "<pyshell#27>", line 1, in <module>
'AB\xff'.encode('ascii')
UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 2: ordinal not in range(128)
---- unicode string:
>>> u'AB\xff'.encode('ascii')
Traceback (most recent call last):
File "<pyshell#28>", line 1, in <module>
u'AB\xff'.encode('ascii')
UnicodeEncodeError: 'ascii' codec can't encode character u'\xff' in position 2: ordinal not in range(128)

'AB\xff'.encode('ascii') raises a UnicodeDecodeError because the byte string 'AB\xff' is decoded from the default encoding (sys.getdefaultencoding(), which is 'ASCII' in most cases), before the .encode() method is called.
This is not a Python bug, but it is surprising. You should try Python 3 which does not have implicit conversion from/to bytes/unicode.
