Question

Here’s my problem, I have a variable wrongly encoded that I want to fix. Long story short, I end up with:

myVar=u'\xc3\xa9'

which is wrong because it’s the character ‘é’ or \u00e9 UTF-8 encoded, not unicode.

None of the combinations of encode/decode I tried seem to solve the problem. I looked towards the bytearray object, but you must provide an encoding, and obviously none of them fits.

Basically I need to reinterpret the byte array into the correct encoding. Any ideas on how to do that?
Thanks.

What you should have done.

>>> b='\xc3\xa9'
>>> b
'\xc3\xa9'
>>> b.decode("UTF-8")
u'\xe9'

Since you didn’t show the broken code that caused the problem, all we can do is make a complex problem more complex.

This appears to be what you’re seeing.

>>> c
u'\xc3\xa9'
>>> c.decode("UTF-8")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/encodings/utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

Here’s a workaround.

>>> [ chr(ord(x)) for x in c ]
['\xc3', '\xa9']
>>> ''.join(_)
'\xc3\xa9'
>>> _.decode("UTF-8")
u'\xe9'

Fix the code that produced the wrong stuff to begin with.
