The emoji with the official Unicode name THUMBS UP SIGN is đź‘Ť.
Unicode identifies this character as U+1F44D. In ordinary communication, it commonly expresses approval, agreement, encouragement, or that something is acceptable. Its visual design is a hand with the thumb raised, although details such as skin tone, shading, and orientation vary by platform.
THUMBS UP SIGN is the base emoji character. Unicode also supports skin-tone modifier sequences for many human-form emoji, so users may see versions with different skin tones. Those variants do not change the underlying gesture’s basic meaning.
The symbol is distinct from CLAPPING HANDS, HANDSHAKE, and OK HAND SIGN. Context can influence tone—some cultures or conversations may interpret a thumbs-up differently—but the Unicode name identifies the encoded character, not every possible social meaning.
