U+3357 "㍗" Square Watto Unicode Character

U+3357 "㍗" Square Watto is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the Japanese unit of power known as "watto," which is the Japanese pronunciation of the English word "watt." It is designed as a square or monogrammed form of the characters "ワ" (wa) and "ト" (to), effectively combining them into a single compact symbol for use in East Asian text, particularly in contexts where space is limited or a stylized representation is desired. This character belongs to the "CJK Compatibility Ideographs" block, which was primarily included for roundtrip conversion with older character encodings, and it is not typically used in modern standard writing but may appear in historical or specialized documents.
