The above link shows two handfuls of I suppose address schemes for 
that sign, U+8072 in unicode.

For me, the name

* <CJK Ideograph>
* CJK IDEOGRAPH-8072

is better than "No match" and I get the majority of people who never 
process any CJK will suffer performance-wise were the horde of CJK 
characters to match in part on insert-char.  So, an opt-in toggle and 
filter improves on the situation of a blank drop.

Maybe the relevant U+8072 slab from Unihan_Readings.txt can be 
included in describe-char under "Unicode data".
