𖿰

Alternative forms
There are two different stylistic variants of the mark. The more common is as (but the bottom hook may be omitted) and the other is as.

Diacritical mark

 * 1)  dấu cá is used to indicate an alternate reading, usually a reading not received from Chinese.

Usage notes
The reading mark combines with the preceding Han character in such a way that the character and the mark together are as wide as a usual character; for example a combination of and ◌𖿰 would yield ⿰日​亇 (𪰇), and the pronunciation would change from  to. However, not many fonts correctly support this mark.
