Change IDS to ⿰𫵖吉

Agree with #7734

I have a suspicion that it might be misprinted form of U+21CDB 𡳛. Is it known where this character originally appears?

We don't currently have an original source for this. It is possibly a misprint. "cứt" means "excrement", so an appropriate semantic would be 屎 (thỉ), as in U+21CDB 𡳛. The analysis shown in the entry above says VN-F0156 is composed of "thỉ cát" (cát is the phonetic). There are no known readings for ⿸尸示 in Vietnamese and it's unlikely that it ever appears in a Vietnamese context. The author of the "Giúp đọc Nôm và Hán Việt" surely meant 屎 in his analysis.

屎 reads thỉ in Vietnamese (HV), and 示 reads thị (HV), that means only the tones are different.

If we treat 𫵖 as the variant of 屎, 示 is the phonetic element of 𫵖 only for this usage.
