U+2121 "℡" Telephone Sign Unicode Character

U+2121 "℡" Telephone Sign is a typographic symbol representing a telephone, often used in older signage, business directories, and telecommunications contexts to indicate a phone number or a place where a telephone can be found. It is part of the Letterlike Symbols block, which includes characters that resemble letters but serve as symbols for specific concepts. The character is encoded as a single glyph, distinct from a combination of the letters “TEL,” and is particularly common in Japanese and East Asian advertising and informational displays. Its inclusion in Unicode ensures consistent representation across digital platforms, preserving a classic icon of communication before emoji and modern telephone icons became widespread.
