U+3311 "㌑" Square Ginii Unicode Character

U+3311 "㌑" Square Ginii is a CJK (Chinese, Japanese, and Korean) compatibility ideograph, specifically a squared form of the Japanese katakana word "ギニー" (ginii), which itself is a phonetic transcription of the English word "guinea." This character belongs to the "CJK Compatibility" block, a set of characters encoded primarily for compatibility with older East Asian text encodings, where it represents a unit of currency or a historical reference to the guinea coin in a compact, square-shaped display. It is used in vertical text layouts or specialized typographic contexts, but its usage is largely historical or technical, as modern text processing often handles the full-width or normal katakana spelling instead.
