The usual low-numbered control characters are replaced with
"\n" escapes ( n, r, b, v, f ).

Anything outside the range 32 to 126 inclusive is replaced with
"\ddd" octal escapes _unless_ the char is > 127 and the
"print_topbitchars" option is set.


Logging is not intended as input for automated parsing, but for
humans... and has a western bias. In particular it knows
nothing about UTF-8. There's an open bug in the area, 282, which
wonders what ought to be done.
