表情符号无障碍性

让残障人士能够无障碍使用表情符号，包括屏幕阅读器描述、无障碍设计以及具有代表性的表情符号。

Emoji accessibility encompasses several aspects:

**Screen readers**: When a screen reader encounters an emoji, it reads the Unicode name (e.g., "grinning face with smiling eyes" for 😄). Overusing emoji can make content tedious for screen reader users.

**Representation**: Emoji 12.0 (2019) added accessibility-themed emoji including wheelchair users, prosthetic limbs, hearing aids, guide dogs, and a person with a white cane.

**Design**: Emoji should be visually distinguishable for users with color vision deficiencies. Skin tone modifiers also serve an accessibility function by enabling representation.

Best practices include using emoji to complement (not replace) text, avoiding emoji-only messages, and testing with screen readers.
