U+33FF "㏿" Square Gal Unicode Character

U+33FF "㏿" Square Gal is a CJK compatibility ideograph that represents the unit of volume measurement known as the "gal," which is an abbreviation for gallon, encoded as a single square glyph (㏿) for use in East Asian text, particularly in contexts where units are traditionally written enclosed in a square format. This character is part of the CJK Compatibility block, which was designed to preserve the visual appearance of legacy character sets that combined multiple letters or symbols into one cell, ensuring consistent display in environments like older Japanese or Chinese computer systems. It specifically encodes the unit "gal" rather than the full word "gallon," allowing for compact representation in technical or measurement contexts.
