Thanks.  Neither work as I expect.  It seems that \0 does not work in char 
classes.  Could you please try this also?

perl -p -e 's{(\0|[\200\210\360\377])}{sprintf "\\x%02x", ord($1)}ge' <log 
>out.3

Currently your output looks like this:

tests/testsuite.dir/004/input.y:1.11: error: invalid null character
    1 | %header "\xf0\x80\x88"
      |           ^

the expected output should also show \x00:

    1 | %header "\xf0\x00\x80\x88"
      |           ^
