CHECK THE BOLD MESSAGES

I don't know if this is a common prob to everyone and if this will be the longest Issue ever but I'll try to make it short but still providing the error and the codes:

The Error:

It's literally told there that the problem is libiconv.dll. I will not show my project because it's literally obvious what the problem was. And yes, the file is not in the incorrect path nor corrupted.

This is the unedited code code from zbar_library.py:

This is what error I got now from editing line 59 and 61:

Almost the same but I change the code with the constructor syntax now. I have been researching from here in github, in other websites, and still didn't find anything to fix this. Can someone from the devs help me here?

P.S. Also do not include #13 and #73 here. That still did not work. I also tried the opinions from #93 (Because it's similar to that) but still got 0% in the improvement. (btw i know not related to the problem but still concerned me, why is the ones of the issues similar...?)

I just followed stackoverflow and solved it on my computer

1. down pyzbar-0.1.9-py2.py3-none-win_amd64.whl in https://pypi.org/project/pyzbar/#files
2. unzip .whl file
3. move libzbar-64.dll and libiconv.dll to Lib\site-packages\pyzbar\
