[Message part 3 (text/plain, inline)]

I have used the "unix" sort for years without trouble, but suddenly 
something weird is happening. I have a student whose last name is Khan, 
and a student whose last name is Khanal,. The comma immediately follows 
the last name. Obviously Khan should be sorted before Khanal, both from 
the English standpoint and based on the ASCI code for a comma. But it is 
not. Khanal comes first. Why?
(The two files I have attached are the unsorted version (khan.txt) and the 
one produced by
sort +0.0  -0.14 khan.txt >khan.out

                         Dr. Betty Barr,
                         University of Houston

Glad to hear it.  Yes, it is rather a shock when upgrading a system
changes the default locale to something different than it was before,
with all sorts of knock-on effects that many people are not expecting;
but it's nothing that coreutils can change other than to help teach
people about the effect of locale settings.
