UnicodeDecodeError on my mp3 about tinytag HOT 5 CLOSED

Hi ibeex,
Thanks for your report!

I have got an idea why it doesn't work, so if you've got the time, please try to change line 230 from

return self._unpad(codecs.decode(b[3:], 'UTF-16'))

to

return codecs.decode(self._unpad(b[3:]), 'UTF-16')

Changing the code as shown above will first remove the zero-termination byte and then decode the string, instead of doing it the other way around.

Since UTF16 always expects get 2 bytes per character as input, but the byte string may be zero-terminated, making giving the bytestring an odd length, so there's a byte "missing", leading to truncated data.

Still the same, I am not sure that this mp3 is actually utf-16, mediainfo can read tags but all python libs can't read artist, album tags.
here is new error

Ok, could you please upload the MP3 somewhere, so I can try to find out the problem on my own?

Hey @ibeex, I have fixed the problem and added the first few bytes of the mp3 you send to the test suite. Please try it out again now, and feel free to reopen this issue, or open another one, if you find something :)
