Only if you use index() on character strings - if you use index on byte
strings it returns a byte position. So just read the file in binary,
convert your search string to the same encoding and invoke index().

Caveat: Some encodings are ambiguous: The same character sequence may be
represented by different byte sequences. For those encodings, index
won't work.
