U+3387 "㎇" Square Gb Unicode Character
Unicode Version 17.0
㎇
U+3387 "㎇" Square Gb is a precomposed CJK (Chinese, Japanese, and Korean) compatibility ideograph representing the unit abbreviation for gigabyte, specifically the square version of the Latin letters "G" and "B" combined into a single character. It is primarily used in East Asian text environments where space or typographic consistency is a concern, appearing in contexts such as digital storage capacity labels or technical documentation. This character is classified under the "CJK Compatibility" block in Unicode, meaning it was included to maintain roundtrip compatibility with older encoding standards rather than for general modern use.
