Alternative forms

In mainland China (based on Xin Zixing character form), Japanese kanji, Korean hanja and Vietnamese Nôm, the upper right component 𠫓 is written ⿱亠厶 (4 strokes) while the bottom right stroke is written 乚 with an ending hook which is the historical form found in the Kangxi Dictionary.
In Taiwan and Hong Kong (based on Big5 character form), the upper right component 𠫓 is written ⿻一厶 (3 strokes) while the bottom right stroke is written ㇄ without the ending hook.

- U+FA97 corresponds to an alternative form used in North Korea which is similar to the character used in Taiwan/Hong Kong.
- U+2F902 corresponds to an alternative form used in Taiwan which is similar to the character used in mainland China/Japan/Korea but the bottom right stroke is written ㇄ without the ending hook.
