U+3343 "㍃" Square Maikuro Unicode Character

U+3343 "㍃" Square Maikuro is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents a squared form of the Japanese katakana rendering for "maikuro," which is the transliteration of the English word "micro." It is part of the "CJK Compatibility" block, specifically designed for compatibility with older East Asian character encoding standards, and is often used in contexts like representing the metric prefix "micro-" in compact text or signage, such as for units of measurement. Unlike standard CJK Unified Ideographs, this character occupies a single square designed to fit within a fixed-width text grid, making it a typographic convenience rather than a traditional logograph.
