Isn't Buddhist Bayeux recorded in Sanskrit of ancient India? How to look a bit like Burmese characters! ! ! What's going on here? Very puzzled

Yes, the Bayeux Sutra in your picture is indeed in Burmese. First of all, Buddhism in Southeast Asia is called Pali Buddhism, so the earliest Buddhist classics introduced to Southeast Asia were written in Pali, not in Sanskrit. Secondly, the Buddhist scriptures recorded in Bayeux are traditional, but not all of them are Indian original texts, and Buddhist scriptures will only be circulated after translation. Not everyone is proficient in Indian Sanskrit or Pali, but of course they will write in Burmese.
