U+337B "㍻" Square Era Name Heisei Unicode Character

U+337B "㍻" Square Era Name Heisei is a precomposed CJK (Chinese, Japanese, and Korean) square character that represents the Japanese era name Heisei, which corresponds to the reign of Emperor Akihito from January 8, 1989, to April 30, 2019. It was included in Unicode as part of the "CJK Compatibility" block, which encodes characters that were originally used in East Asian text systems for vertical or squared typography, allowing the two-kanji compound "平成" to be displayed as a single, fixed-width glyph for compatibility with older character sets and legacy systems. This character is rarely used in modern digital text, but it may appear in historical documents, stamps, or special typographic contexts where era names are written in a compact, standardized form.
