    result, err = p.communicate(self.view.substr(self.view.sel()[0]).encode('utf-8'))

    # gave up trying this approach: result always has '\n' strings in it that refuse to render
    #result = json.dumps( self.view.substr(self.view.sel()[0]), indent=2)

    # http://code.activestate.com/recipes/65211/  seems to say that Python "ruins" non-raw strings by 
    # actually placing '\','n' in the friggin string unless it's marked 'raw'?  Is that true?  Shouldn't a string be a string
    # and the raw/not raw output be a function of the runtime?  Why does "print" have some magic to reescape these strings and
    # yet there are no other buffer objects that seem to do it (aka StringIO or BytesIO).

    if result != "":
      self.view.replace(edit, self.view.sel()[0], result.decode('utf-8'))
      sublime.set_timeout(self.clear,0)

Thank you for your work! Had a huge JSON file and this was a big help.
