-1 on doing that when they're printed (although I probably misunderstand
what you mean there).
+1 for changing repr() as suggested.
-0 on generalizing to \a \b \f \v too (I've never used one of those in a
string literal in my life, so would be more baffled by seeing one come back
than I would the octal equivalent).
I would also be +1 on using hex escapes instead of octal (I grew up on 36-
and 60-bit machines, but that was the last time octal looked *natural*!).
Octal and hex escapes both consume 4 characters, so I can't imagine what
octal has going for it in the 21st century <wink>.

PS: Note that C doesn't define what numerical values \a etc have, just
that:
 Each of these escape sequences shall produce a unique
 implementation-defined value which can be stored in a single
 char object. The external representations in a text file need
 not be identical to the internal representations, and are
 outside the scope of this International Standard.
The current method does have the advantage of extreme clarity.
