hexadecimal replacing with awk ?
Hi there !

I have text files with some nonsense characters in it, so different text editors put different nonsense symbols, and, worse, the application that should be able to read these files doesn't.

With xxd, the nonsense characters show as "efbfbd", while they should be "c2a7" (the 'paragraph character', §).

E.g., this is a line of xxd output containing the weird character :
Code:
0000260: 3433 3036 312c efbf bd28 2244 4941 4e54  43061,...("DIANT

Now, is there a way to change the "efbfbd" into "c2a7" ? Preferably with awk, since that's what I'm using to treat these files with for other purposes.

Thanks !
jos
