Yeah, I did consider having to try the permutations until it works, but suspecting that somebody takes "utf8" without taking "UTF-8" is to pretty much invalidate the basic premise of the existing code, i.e. spelling it as "UTF-8" is the most likely to work anywhere as long as UTF-8 is supported, so I stopped worrying about it at that point. I'd actually welcome a more generic suggestions we can put in our documentation so that we can _lose_ the fallback entirely (e.g. "if your contributor spelled 'utf8' and your system, which does take 'UTF-8', does not like it, then here is what you can do to your /etc/locale.alias").
