U+3329 "㌩" Square Notto Unicode Character

U+3329 "㌩" Square Notto is part of the CJK Compatibility block and represents a square version of the Japanese katakana word "ノット" (notto), which is the loanword for "knot," a unit of speed used in maritime and aviation contexts. This character is primarily used in East Asian text environments, such as Japanese typography, where it appears as a single wide ideograph for compact display in maps, charts, or other specialized media. Its inclusion in Unicode ensures compatibility with older character sets that encoded such squared katakana sequences as distinct glyphs for space efficiency.
