李明锡 is a typical East Asian three-character name reading:
李 (Lǐ, 이/Lee — one of the most common Korean and Chinese surnames) +
明锡 (Míngxī, 명석 — Korean Myung-seok, 'bright + tin/pewter', a common male given name). In Chinese subtitles for Korean dramas, hanja-based names are converted to Mandarin readings rather than romanized.
