Compatibility form of 嗀

It represents 嗀, an old Chinese word for vomiting.

Chinese dictionaries gloss 嗀 as “to vomit,” though its readings vary across traditions. A bronze inscription from the late Western Zhou period attests the graph. The later Chinese dictionary Shuowen Jiezi explains it and quotes a passage from China's Spring and Autumn period.

Big5, a Traditional Chinese character encoding, mapped 嗀 twice. 嗀 preserves the duplicate mapping when old Big5 text is converted to Unicode and back. Compatibility normalization can change 嗀 to 嗀. A font without support may show a different fallback shape.
