A common Korean masculine given name written 헌우/현우 (Heonwoo / Hyunwoo) — Korean names are often transcribed back into the original Chinese characters (Hanja) rather than transliterated.
宪 means "constitution / law" and
宇 means "universe / cosmos," so the Hanja meaning reads roughly "upright cosmos" — a wholesome, scholarly choice. K-drama actor Park Hyun-woo (박헌우) is one bearer.
