Hi Luka,
I just want to let you know that I appreciate your frequent reports.
I intend to take a look at your latest code during the weekend.

This applies to C sources as well, and to some other languages. My
approach to dealing with it is generally to split/concatenate the string
right after the escape sequence, like this:
const char *k = "\xff\xa3" "34" "\xff\xff\xff\xa3" "345";
(from some code I wrote yesterday).
I think this one was actually OK without the splits, but better safe
than sorry - and like you say with octals the problem is more real.
