Yeah, romanizing Asian names is done poorly to be honest. I saw it a lot in Korea. They had this 'official' system that they followed, but to be honest it mostly caused more issues. The common joke at the olympics was the Korean guy named suk, but it was pronounced more like sock than suck. and if they'd just spelled it like that , it would eliminate those jokes entirely. Spelling it pawn or pon would eliminate that connotation completely.
