We're coming up on when Python2 is end-of-lifed - we have until January 1st 2020. git-p4 uses python2, and doesn't work under python3 at all. The problem is the conversions between Python3 unicode strings and git (utf-8) and p4 (utf-8, except when it isn't). I had a go at fixing this here: https://github.com/luked99/git/commits/git-p4-python3-final-showdown You can see from the comments that I wasn't really finding it straightforward. I think I know a bit more about the problem now, but before I start having another go at fixing this, I wondered if anyone else had any thoughts on this, or even better, some time to spend on this. Thanks Luke
