Quich answer.

That's PyShell, the wxPy interpreter.

You are right in pointing all this missmatch: byte string,
unicode, utf-8, mixing a "unicode" tool kit wiht a non
unicode native engine, plus plenty of related things, ...

You may be not aware. I contributed to wxPython from
practically 2.0, 2.1. 2.2 during 6, 7, 8 yeaurs, testing,
reporting about/with all versions, then I gave up.

Yout quote.
"Even if it is true that wxPython cannot handle Unicode text..."

It's a confusing vision and that's not correct. It's a little bit
more complicate than this.
