Emoji

Small pictographic characters — faces, gestures, objects, symbols — encoded as Unicode code points and rendered by platform-specific font sets, used to convey affect, tone, and non-verbal nuance in otherwise text-based or visually-limited communication. For accessibility, emoji are double-edged: they are announced aloud by screen readers using Unicode descriptions (which can be verbose, unexpected, or mismatched with intended meaning — e.g., a 😂 announced as 'face with tears of joy'), and heavy emoji usage or decorative emoji strings can severely degrade the listening experience. At the same time, emoji have become an expressive resource for disabled users (AAC users, deaf TikTok creators, blind social-media users) precisely because they encode affective content at low typing cost. Guidance for accessible emoji use includes sparing placement (generally at the end of messages rather than between words), avoiding decorative strings, and testing with actual screen-reader output.
