Alas, we can't change the behavior; it is mandated by POSIX:
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/od.html

-c
    [XSI] [Option Start] Interpret bytes as characters specified by the
current setting of the LC_CTYPE category. Certain non-graphic characters
appear as C escapes: "NUL=\0", "BS=\b", "FF=\f", "NL=\n", "CR=\r",
"HT=\t"; others appear as 3-digit octal numbers. [Option End]
