The glyph doesn't match it's evidence. What's more, some UTC glyphs are too ugly to see and I can't stand if we add these to code chart.

The glyph should be modified to match the IDS and evidence as below.

The upper-right component of the representative glyph will be changed from 力 to 刀 to match the evidence and IDS.

I suspect this is an typographical error of 啗. Asian printed publication before personal computers usually transcribes from author's handwritten draft, so such things tend to happen. Moreover, this is a modern (almost contemporary) dictionary explaining a quite basic word. Do we have appearance in the actual world outside of this dictionary?

I also suspect this is a typographical error for 啗. It's not uncommon for handwritten form of 臼 to be written in a form similar to 血; further corruption to 皿 is definitely plausible. I suggest UTC to withdraw this unless there is other evidence of such use.

The UTC will withdraw this character.

Confirmation that the correct form of the character is ⿰口⿱刀臼 (unifiable with U+5557 啗).
