U+3339 "㌹" Square Herutu Unicode Character

U+3339 "㌹" Square Herutu is a CJK compatibility ideograph that represents the Japanese word "herutu," an abbreviation for the English word "helts" or a shift of "health," and is part of a set of square-format characters used to fit Latin-derived terms into a monospaced East Asian text grid. Specifically, it combines the katakana syllables "he" (ヘ), "ru" (ル), and "tu" (ツ) into a single square block, historically appearing in legacy Japanese computer systems like the JIS X 0208 standard to encode common foreign loanwords compactly for displays with fixed-width character cells. Today, it is primarily relevant for text encoding compatibility rather than active everyday use.
