The logical set shoule include -w, and, probably, -B.

To quote FreeBSD ls(1):

     -B      Force printing of non-printable characters (as defined by
             ctype(3) and current locale settings) in file names as \xxx,
             where xxx is the numeric value of the character in octal.

     -b      As -B, but use C escape codes whenever possible.

     -q      Force printing of non-graphic characters in file names as the
             character `?'; this is the default when output is to a terminal.

     -w      Force raw printing of non-printable characters.  This is the
             default when output is not to a terminal.

     The -B, -b, -w, and -q options all override each other; the last one
     specified determines the format used for non-printable characters.
