Yes, but GitHub has its own problems. I'd rather stick with email, just 
as many other projects use email for this sort of thing. Also, I've been 
thinking of moving the development repository off GitHub for other 
reasons, and I don't want to rely on GitHub-specific features.

Fewer and fewer programs default to ISO 8859 these days, so any advice 
we'd add would be for a dwindling number of old-fashioned clients. We 
shouldn't need to change the development process for them.
