U+3345 "㍅" Square Mahha Unicode Character
Unicode Version 17.0
㍅
U+3345 "㍅" Square Mahha is a CJK (Chinese, Japanese, and Korean) compatibility ideograph representing a square-format abbreviation for the Japanese word "マッハ" (mahha, the Japanese transliteration of "Mach," as in Mach speed). It is part of a set of precomposed characters designed for compatibility with older East Asian character encodings, primarily used in contexts like vertical text or limited-width displays where a single character space is needed. In modern usage, this specific square form is rarely employed in everyday writing, as the standard spelling "マッハ" is preferred, but it remains a functional part of digital text encoding for historical and legacy system support.
