pyRevit cannot load, if certain unicode symbols in configfile

[melnikovalex]

Describe the bug
Hi Ehsan! I am going to continue topic with unicode chars. It is similiar to #511 but looks much more strange. I'll explain why.

To Reproduce
So to crash pyRevit on start, just add these lines to config (symbol is S ligature - ß)

[TestConfigconfig]
x = "\u00df"

Okay, everything could happen with unicode and python. But! The strange thing - if you change it to another unicode symbol - let's say cyrillic Ы - and restart revit, it works again!

[TestConfigconfig]
x = "\u042b"

I am using json.dump to create string repr for the config values. It was set to enforce ASCII and it would break on some unicode characters (doesn't happen in cpython). Resolved this. See the commit and grab the revised configparser.py or pull the release/4.6.24 for testing.
