I think I wasn't clear in saying

聲 CJK UNIFIED IDEOGRAPH 8072

is meaningful to me, better than "no match".  The tangent to 
Unihan_Reading.txt provides more meaning than the address scheme 
label "CJK UNIFIED IDEOGRAPH" which to Po Lu is arbitrary and 
meaningless.  For me, the label

* LINEAR A SIGN
* CJK UNIFIED IDEOGRAPH

puts meaning on the four digit hex value used in Unicode, as it is 
being typed

* 8
* 80
* 807
* 8072
