<p class="MsoNormal">'mbcs' is what python uses to mean the current configured encoding. I would guess that the encoding of sys.stdout is different when using visual studio output console than the console.<o:p></o:p></p>

<p class="MsoNormal"><br>
You could try a different encoding method by setting the PYTHONIOENCODING environment variable before starting your exe, eg:<o:p></o:p></p>
<div>
<p class="MsoNormal">SET PYTHONIOENCODING=utf-8:ignore<o:p></o:p></p>
