I want to ask. Not really about translation but romanization. Is を better romanized as "wo" or "o"? I often see は written as "ha" and へ as "he". Also, what about words breaking (example like どうするんだ, better be romanized as "dou suru nda" or "dousurunda" or "dou surun da")? Please give me your opinion.
