latter results in the tool showing a "normalized IDS" which is the 
former.  It appears that the tool is, of necessity, performing its own

Then there's unification issues.  For example, this recently added 
Extension G character:
U+31310    𱌐    ^⿰鼠𠔥$(G)    ^⿺鼠𠔥$(Z)

and I don't know how or if that would be addressed.

IDS are useful for expressing unencoded ideographs in plain-text, not 
only for those rare older characters, but also for newly invented ones.
