REVISION SUMMARY
  The tranformer does append b'' to the value and make that a bytes but bytes in
  Python 3 returns the ascii value on getting characters using indexing.
  Characters of this string are queried using indexing multiple times in the file
  and to support that we use pycompat.bytestr which returns the bytechrs using
  indexing.
