如何使用python将utf-8字符串转换为big5？

Question

I use Python 2.6.6 My locale is ('en_US', 'UTF8')

I try many ways to convert utf-8 string to big5, but it can't work. If you know how to do that, please give me some advice, thanks a lot.

A chinese word called '單車', it mean 'bicycle'

It's unicode is \單\車

str_a = u'\u55ae\u8eca'
str_b = '\u55ae\u8eca'
print str_a    # output '單車'
print str_b    # output '\u55ae\u8eca'

I know the str_a can be work, but I want to convert str_b to big5, too.

I try out decode, encode, unicode, but it still can't work.

Have any good idea? Thanks.

Answer 1

str_b is a sequence of bytes:

In [19]: list(str_b)
Out[19]: ['\\', 'u', '5', '5', 'a', 'e', '\\', 'u', '8', 'e', 'c', 'a']

The backslash and u and so forth all are just separate characters. Compare that to sequence of unicode code points in the unicode object str_a :

In [24]: list(str_a)
Out[24]: [u'\u55ae', u'\u8eca']

To convert the mal-formed string str_b to unicode decode with unicode-escape :

In [20]: str_b.decode('unicode-escape')
Out[20]: u'\u55ae\u8eca'

In [21]: print(str_b.decode('unicode-escape'))

Answer 2

You should be able to do this:

str_a = u'\u55ae\u8eca'
str_b = str_a.encode('big5')
print str_a
print str_b.decode('big5')
