You aren't actually looking at the content of a "strange file".
You're trying to see its name.  For this specific case, you may want
"ls -b" instead.

-rw-r--r--   1 wooledg    pgmr             0 Nov 30 08:39 \011

Or from Linux:

arc3:~$ ls -lb ?
-rw-r--r-- 1 wooledg voice     0 2009-11-30 08:39 \t
