U+3398 "㎘" Square Kl Unicode Character

U+3398 "㎘" Square Kl is a precomposed CJK Compatibility Ideograph that represents the unit of measurement "kiloliter," abbreviated as "kL" or "Kl" in a square format. It was included in Unicode to maintain compatibility with legacy East Asian character sets, such as those used in Japanese, Chinese, and Korean text, where such squared unit symbols were commonly printed as single characters. This character specifically denotes 1,000 liters and is part of a larger collection of squared Latin and Greek unit abbreviations, like "㍍" for meter or "㌢" for centimeter, designed for compact display in contexts like labels, charts, or technical documentation.
