It's Peking, Bombay, Calcutta, Burma and Turkey, not Beijing, Mumbai, Kalkotta, Myamar or Turkiye. Beijing, Mumbai, Kalkotta, Myamar and Turkiye still won't sound like the locals pronounce it when a native English speaker says it, so what's the point in changing to a more phonetic spelling? All the cities and countries were originally written down in a different alphabet, so they were not miss-spellings. We don't demand the French call Londres London or Douvres Dover. The Germans don't demand we call Cologne Koln or Bavaria Bayern.
