It's not clear to me whether you understood my earlier point.  Your setting 
of LC_ALL breaks things because it has the side effect of implicitly 
changing LC_NUMERIC.  By explicitly setting LC_NUMERIC as I've described, 
you'll work around the problem while still achieving the (hopefully) 
desirable effects of setting LC_ALL.

Incidentally, if setting LC_ALL doesn't achieve the desired effects (you're 
running an old enough version that it's not very convenient for me to check 
the behavior myself) you may also want to try setting the option Formatting 
Options->Font Options->CharacterEncoding at global scope in the option
