U+22DAF, or CJK UNIFIED IDEOGRAPH-22DAF doesn't seem to have a glyph inside of noto-cjk. There isn't too much info to give here other than the fact that it seems like very few fonts support it in general? I've struggled to find much information about the glyph in general, but it's a part of Unicode, and several pieces of Simplified Chinese text seems to use it.

The specific sample I originally found it in is here: https://github.com/rjtngit/rawchars/blob/master/Chinese-Simplified.txt, the third to last symbol.

zi.tools has a reference for it, here: https://zi.tools/zi/%F0%A2%B6%AF
as well as in the standard Unicode charts here: https://www.unicode.org/charts/PDF/U20000.pdf
