I need an intuitive sort order, and that is the one given by the ASCII collating sequence. It was interesting, because some applications were getting it right, and some were providing goofy results:
- Dot should be before letter or digits.
- Upper case should precede lower case. They should not be intermingled.
- Digits should be treated as digits, not as numbers. E.g., 10 should appear before 5, since '1' appears before '5' in the collating sequence. The problem here is that someone is trying to predetermine how I name files or interpret file names.
The fix is easy. My /etc/default/locale was just one line. I added the second, logged out, and logged back in:

However Caja 1.6.1 still doesn't sort file names correctly.
