Malaysian RT
I have flown in Malaysia (indeed very recently) and I can assure you, everyone speaks English, even locals to locals. Not always easy to understand their accents, but I have heard very little "jargon". I even tried to say "salamat pagi" on first contact with ground one morning and they came back with "good morning." Based on my experience, the transcript is nonsense and all instructions, whether commercial or GA flying are fully ICAO.
