I would like to make the test more robust (per 8008761), though my focus 
at the moment is to avoid a test failure on our automated test systems, 
which all use "C".

I've made a note in 8008761 that we should check for other locales that 
do not use UTF-8.

Good point - I'll check LC_ALL first.

Updated webrev with re-ordered LC_ALL check (and "LC_ALL=" output 
change) is here:
