U+3374 "㍴" Square Bar Unicode Character
U+3374 "㍴" Square Bar is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the unit "bar" for atmospheric pressure, specifically a square-format abbreviation used for concise presentation in East Asian text. Encoded in the Unicode block for CJK Compatibility, it is derived from the Japanese katakana writing style where the character for "bar" (バー) is compressed into a single square-shaped glyph to match the visual dimensions of other CJK characters. This symbol is primarily employed in technical and scientific contexts, such as on pressure gauges or in documentation, where it serves as a typographic alternative to the standard Latin abbreviation to ensure visual harmony within a line of Chinese or Japanese characters.
