Python: Convert Unicode-Hex-String to Unicode

Question

I have a hex-string made from a unicode string with that function:

def toHex(s):
    res = \"\"
    for c in s:
        res += \"%02X\" % ord(c) #at least 2          


        

Answer 1

Can't be done. Using %02X loses too much information. You should be using something like UTF-8 first and converting that, instead of inventing a broken encoding.

>>> u"Knödel".encode('utf-8').encode('hex')
'4b6ec3b664656c'
