converting binary to utf-8 in python

问题

I have a binary like this: 1101100110000110110110011000001011011000101001111101100010101000

and I want to convert it to utf-8. how can I do this in python?

回答1:

Cleaner version:

>>> test_string = '1101100110000110110110011000001011011000101001111101100010101000'
>>> print ('%x' % int(test_string, 2)).decode('hex').decode('utf-8')
نقاب

Inverse (from @Robᵩ's comment):

>>> '{:b}'.format(int(u'نقاب'.encode('utf-8').encode('hex'), 16))
1: '1101100110000110110110011000001011011000101001111101100010101000'

Well, the idea I have is: 1. Split the string into octets 2. Convert the octet to hexadecimal using int and later chr 3. Join them and decode the utf-8 string into Unicode

This code works for me, but I'm not sure what does it print because I don't have utf-8 in my console (Windows :P ).

s = '1101100110000110110110011000001011011000101001111101100010101000'
u = "".join([chr(int(x,2)) for x in [s[i:i+8] 
                           for i in range(0,len(s), 8)
                           ]
            ])
d = u.decode('utf-8')

Hope this helps!

>>> s='1101100110000110110110011000001011011000101001111101100010101000'
>>> print (''.join([chr(int(x,2)) for x in re.split('(........)', s) if x ])).decode('utf-8')
نقاب
>>> 

Or, the inverse:

>>> s=u'نقاب'
>>> ''.join(['{:b}'.format(ord(x)) for x in s.encode('utf-8')])
'1101100110000110110110011000001011011000101001111101100010101000'
>>>

Use:

def bin2text(s): return "".join([chr(int(s[i:i+8],2)) for i in xrange(0,len(s),8)])


>>> print bin2text("01110100011001010111001101110100")
>>> test
