Your reminder of the difficulties in Unicode, and the URLs are much
appreciated. In particular, the keyword 'while' in Arabic should be
written Left-To-Right, even though the ambient text is Left-To-Right.

I've found these URLs, which suggests that there's a still a problem
to be solved.

My understanding is that at present it's not straightforward to
provide legible localised text at the Python console, when the locale
language is Arabic, Persian, Hebrew or Urdu. (And another problem is
allow copy and paste of such text.)

If it is straightforward to provide RTL localisation at the Python
interpreter, I'd very much appreciate being pointed to such a
solution.
