Ifso, which locale should I use?

Maybe, not sure. The logical thing to do would be to set LC_CTYPE to 
"English_United Kingdom.65001", which tell Windows to expect UTF-8 
charset. However, old discussions on this subject suggest that Windows 
won't accept that:

It's still worth a try, I think. Things might've changed since then. If 
that doesn't work, you could also try some other random codepages as a 
workaround. If you're lucky, one of them might work better, even though 
it would still be the wrong codepage for UTF-8.
