U+3315 "㌕" Square Kiroguramu Unicode Character

U+3315 "㌕" Square Kiroguramu is a CJK (Chinese, Japanese, and Korean) compatibility ideograph, specifically a squared Katakana word that represents the Japanese abbreviation for "kilogram," combining the syllables キ (ki), ロ (ro), グ (gu), ラ (ra), and ム (mu) into a single, compact square-shaped character. It belongs to the "CJK Compatibility" block, where it was encoded primarily for round-trip compatibility with older Japanese character encodings, and it is used in modern typography to denote the metric unit of mass in a visually unified manner, often found in Japanese text for labels, measurements, and tables where space efficiency is desired.
