I had been making these changes in R-devel after offline
discussions with Linux users for which the original check (using "en_UK.UTF-8")
failed.
What I read below is suggesting that "C.UTF-8" is not okay
either, as a fallback.
It seems we should use "en_US.UTF-8" as fallback instead
(though I assume that won't work in North Korea).
I've committed a version that does that _and_ no longer stops
when that identical() does not give a 'TRUE'.
