This all sounds like a pretty good plan to me - please go ahead and do it ASAP!

My only concern here is that setting up Twisted services on Windows can already be a bit fiddly, and I would almost rather generate potential mojibake by default than fail to run in a way which would be even harder to debug than it already is.  However, even if this is a valid concern, let's not block on it, but figure out a way to fix it after the immediate issue where folks with non-ascii letters in their names can't submit PRs.

Thanks so much for investigating!
