It's 2014.  I think requiring ICU is reasonable at this point.

Orthogonal to this RFC, but I'd be in favor of deprecating all the
non-ICU intl stuff sometime soon.

I don't feel strongly about the u"" requirement, it doesn't make the
world a darker place if we're more permissive.

And I really wish that weren't true. :p
