...and it prints:

SyntaxError: Non-ASCII character \'\\x

You can't do encode on unicode character. Encode is used to translate all character encoded in unicode to other code style. It can't be used to unicode character.

In the controversy way, decode can only used to character not encoded in unicode to translate to unicode character.

If you declare a string with 'u' character before the string, you will get a string encoded in unicode. You can use isinstance(str, unicode) to detect if the str is encoded in unicode.

Try this code below. Hint: in Windows with Chinese version, default code style is "gbk".

>>> a = '哈哈'
>>> b = u'哈哈'
>>> isinstance(a,unicode)
False
>>> isinstance(b,unicode)
True

>>> a
'\xb9\xfe\xb9\xfe'
>>> b
u'\u54c8\u54c8'

>>> a.decode('gbk')
u'\u54c8\u54c8'
>>> a_unicode = a.decode('gbk')
>>> a_unicode
u'\u54c8\u54c8'

>>> print a_unicode
哈哈
>>> a_unicode.encode('gbk') == a
True
>>> a_unicode == b
True

>>> a.encode('gbk')
Traceback (most recent call last): File "", line 1, in UnicodeDecodeError: 'ascii' codec can't decode byte 0xb9 in position 0: ordinal not in range(128)

>>> b.decode('gbk')
Traceback (most recent call last): File "", line 1, in UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)
