\302 is the octal representation of the UTF-8 sequence 0xC2
You have invalid chars in the source. If you don't have any valid non ascii chars in your source, maybe in a double quoted string literal, you can simply convert your file back to ascii with the following command:
tr -cd '\11\12\15\40-\176' < old.c > new.c
It works!
