Period at the end of chat name causes crash

[hbh7]

Hey all,

Not sure how I never ran into this before. Seems that it gave the chat name (shortened) "Book." some weird name (OMCVRV~I) and has now decided to stop doing that. Pulling up the output in windows shows the full chat name but with a floating in the middle period at the end.

The error is as follows:

Traceback (most recent call last):

I suppose I'll look into how to perhaps override the naming scheme but I'm not sure how far I'll get and I'm sure there's a better solution possible.

Thanks

Created #108 as a potential fix for the issue
