WILD GUESSES
#1 (benign)
Your 'apache' user on the bad box has some kind of cool shell color-coding
going on.
The color-coding puts out control characters for directories, users,
permissions, and masks weird-o characters in filenames.
Those control characters, when presented to you in a browser/text rather
than a shell context, show up as funky-ass things like ? and that
diamond-shaped inverse ? thing.
You can diagnose this pretty easily, really.
When you su to apache on the bad box and do "ls -ld /" do you get all
kinds of pretty colors and stuff? Well, there ya go. Make it not do
that.
You're on your own figuring out how to do that. To me, it's just some
magic that's sometimes on some Un*x boxes, and sometimes not, and that's
how life goes. :-) [I don't care enough either way about the color-coding
to find out, much less remember, how to change it either way.]
#2 (panic)
EXTREMELY UNLIKELY:
You've been hacked and the 'ls' binary has been replaced with something
that does something else very weird, but you don't see it under shell
conditions...
#1 is almost for sure the real answer...
But if it's #2, you'd better act carefully.
