      python3 keeps byte strings as type 'byte' (in python2 these strings
      were automatically converted into ASCII strings).

      - In the HDF5 files, the string attributes are all of type 'byte' 

      In order to process these strings, they should be converted to ASCII
      using the decode('UTF-8')

      Args:
        * `var` = any variable

      Returns:
        * converted variable, if variable was of type 'bytes', otherwise return variable

   '''

   if type(var) is bytes:
       return var.decode('UTF-8')
   return var
