Changing sort so that it no longer functions on simple text files as it 
has for 25+ years is a terrible idea. (Yes, I've been using sort on Unix 
for that long.)

If you want an i18n sort (and yes, I've read the other bug reports, so I 
know the "LC_ALL="C" workaround), that's fine. But the DEFAULT behavior, 
when the user does nothing special, should be the same as it has been 
since the beginning of (Unix) time.

This change has broken many scripts, and is causing problems which people 
probably aren't even fully aware of.
