U+213B "℻" Facsimile Sign Unicode Character

U+213B "℻" Facsimile Sign is a typographic symbol representing a facsimile machine or fax transmission, originating from the need for a standard character to denote fax numbers or fax-related information in digital text. It is encoded in the Letterlike Symbols block of Unicode, designed to resemble a stylized combination of the letters "F" and "A" or a simplified fax machine icon. This character is rarely used in modern contexts due to the decline of fax technology, but it remains available for historical or specialized applications, such as in directory listings or legacy documentation.
