But is there a reason I'd want LANG set to en_US.UTF-8 instead of C.UTF-8? As far as I can tell, everything works for me with LANG=C.UTF-8. Other than changing the collating sequence to something I don't want, what does LANG=en_US.UTF-8 get me that LANG=C.UTF-8 doesn't? & as long as I'm showing how ignorant I am... why put the local defaults in ~/.bashrc? My understanding is that ~/.bashrc is called at every shell startup. Seems like that's one of those things that just needs to be set in the login shell, so wouldn't ~/.bash_profile be more appropriate for the locale settings? >> Welcome to the new world order :-0 I tried to figure out why the >> collating sequence changes with the language settings but didn't get >> anywhere beyond the fact that it _does_ change.

Which says the en_US locale collates the upper and lower case letters like this: AaBb...Zz I got that much :) What I don't get is why someone would _want_ the collating sequence to be AaBb... or why that sequence was picked for en_US instead of using the natural order of A-Za-z.
