U+3371 "㍱" Square Hpa Unicode Character

U+3371 "㍱" Square Hpa is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the unit of measurement "hectopascal," abbreviated as "hPa," which is commonly used in meteorology to measure atmospheric pressure. This character is part of a block of squared Latin abbreviations designed for vertical text layout in East Asian scripts, where it occupies a single character width for consistent typographic alignment. Its encoding serves to preserve the original formatting of legacy documents and systems, particularly in Japanese contexts, where such squared forms were widely used in print media and digital displays before the adoption of standard Unicode spacing.
