I believe that particular find/replace should be safe even if other 
bytes represent encoded unicode.

In Python3, if you want to do more, and if you open in text mode, the 
bytes with automatically be decoded, with UTF-8 the default, I believe. 
  Your sample said UTF-8, so that would be the right thing.
