str.find() not returning correct index.

[DreamingInsanity]

Rather than open the file in ascii and ignore errors, I would prefer opening the file in binary and searching for the binary/byte string instead.

I like that idea more, and that was my original route but I couldn't get it to work.

I decided to try again and I have managed to also make it work. I am going to stick with using hex because it doesn't rely on any encoding schemes.
