U+331C "㌜" Square Keesu Unicode Character

U+331C "㌜" Square Keesu is a CJK (Chinese, Japanese, and Korean) compatibility ideograph specifically classified as a square Katakana abbreviation, representing the word "keesu" (ケース), which is the Japanese loanword for "case" (as in a suitcase or container). This character belongs to the CJK Compatibility block, where it was encoded to map pre-composed square forms from legacy Japanese character sets, such as those used in early computing or telecommunication systems. Visually, it appears as a compact, equally sized grouping of Katakana characters "ケ" (ke) and "ース" (su and long vowel marker) arranged into a single, square typographic space, intended for compatibility and display in vertical text or limited-width contexts.
