I'm making a postscript of a bunch of C code, and enscript reports I have 2 non-printable chars

[ 91 pages * 1 copy ] left in a.ps
2 non-printable characters
non-printable character codes (decimal):
128 153

However I couldn't find these chars with grep

grep -r $'\231' *
grep -r $'\200' *

Is there a way to let enscript report which lines contain the non-printable chars?

Maybe this will provide a clue as to how to handle these. It is not an answer: unix.stackexchange.com/questions/18579/… –  Joe Apr 20 '12 at 22:37
    
Found another clue here. The trick is running the files through hexdump first and searching the output. Also found some things about using echo with an unescaped $ to pass raw data into grep. Bottom line, I'm not sure your original grep was correct. stackoverflow.com/questions/4180081/linux-binary-grep unix.com/shell-programming-scripting/… –  Joe Apr 20 '12 at 23:01
