Pyren3, SyntaxWarning: invalid escape sequence '\ '

I see issue #91 (closed) also with:
Python version: Python 3.12.4
PyRen3 commit: fcc34349 (February 25, 2024 at 2:35:03 PM GMT+1)

This is a warning introduced in Python 3.12 to prepare for a future restriction.

C:\pyren-pyren3\main.py:430: SyntaxWarning: invalid escape sequence '\ ' self.root.option_add('*Dialog.msg.font', 'Courier\ New 12')

I have seen this warning also for other pyren files.
