"Like C" could also mean that ASCII characters (and probably all 
characters) are collated in code-point order (so, for example, all 
uppercase ASCII letters come before all lowercase).  Or do you think the 
right way to achieve that minimal extension of the C locale to UTF-8 is to 
set only LC_CTYPE and not LC_COLLATE or LC_ALL?
