U+3314 "㌔" Square Kiro Unicode Character
U+3314 "㌔" Square Kiro is a CJK (Chinese, Japanese, and Korean) compatibility ideograph representing the Japanese word "kiro," which is a phonetic abbreviation and contraction of the foreign loanword "kilogram" or "kilometer." This character belongs to the "CJK Compatibility" block, where it was encoded for compatibility with legacy character sets used in Japanese text processing, particularly for writing unit abbreviations in a single square or tategaki (vertical) layout. It is formed by combining the katakana characters "ki" (キ) and "ro" (ロ) into a single square-shaped glyph, and it is used in contexts like product labels, signs, or documents to denote these metric units succinctly, though in modern usage it is largely replaced by standard character sequences.
