Python: Convert Unicode-Hex-String to Unicode -

i have hex-string made unicode string function:

def tohex(s):     res = ""     c in s:         res += "%02x" % ord(c) #at least 2 hex digits, can more     return res  hex_str = tohex(u"...") 

this returns string one:

"80547cfb4eba5df15b585728" 

that's sequence of 6 chinese symbols.

u"knödel" 

converts to

"4b6ef664656c" 

what need function convert original unicode. chinese symbols seem have 2-byte representation while second example has 1-byte representations characters. can't use unichr() each 1- or 2-byte block.

i've tried

binascii.unhexlify(hex_str) 

but seems convert byte-by-byte , returns string, not unicode. i've tried

binascii.unhexlify(hex_str).decode(...) 

with different formats. never got original unicode string.

thank lot in advance!

this seems work fine:

binascii.unhexlify(binascii.hexlify(u"knödel".encode('utf-8'))).decode('utf-8') 

comes original object. can same chinese text if it's encoded properly, ord(x) destroys text started from. you'll need encode first , treat string of bytes.
