Instinct Crossover Myanmar (Burmese) font support?

The list of supported languages for Instinct 2 (RoW modele) is at 

Languages Selectable on Garmin Instinct Watches | Garmin Customer Support

If you own an APAC (Asia-Pacific) model, the list would differ, but I do not know whether Burmese is included there. You best ask the local Support in one of the APAC countries (or perhaps a fellow user of an APAC model will tell you here). So if you own the RoW model, characters of non-supported languages will be indeed parsed as ????. Instinct 2X and Crossover have both RoW and APAC languages included (no RoW/APAC models for those two), hence you could perhaps upgrade your watch to one of those models.

Yes, mine is APAC model. System language is set to English.

It can show other asian languages just fine for the text messages. Only for the Myanmar text, it shows ????? block.

Is it possible to change the font to support Myanmar font?

If you tell the watch displays ???? instead of the characters, then it looks like this part of unicode fonts is not supported. New fonts cannot be added on the user level, they have to be built into the firmware. I recommend contacting your local support, and requesting it from them, but I am afraid the chances are slim, since the memory of Instinct 2 is very limited, and there is not much room for additional fonts.
