U+3393 "㎓" Square Ghz Unicode Character
Unicode Version 17.0
㎓
U+3393 "㎓" Square Ghz is a CJK Compatibility Ideograph that represents the unit "gigahertz" abbreviated as GHz, formatted as a single square symbol for use in East Asian text environments where vertical writing or compact space constraints are common. It was encoded in Unicode to maintain compatibility with older character sets used in Japanese, Chinese, and Korean documents, allowing the unit of frequency equal to one billion hertz to be displayed consistently alongside other squared units like ㎐ for hertz or ㎑ for kilohertz. This character is distinct from a regular sequence of letters "GHz" and is primarily intended for legacy data interchange rather than modern typographic usage.
