Please then answer a simpler one:

When the matching algorithm you envision encounters a character where the 
tables do not tell what to do about it, what will the algorithm do to it?
Pass it through unmodified? Reject it? Does something else which you have 
not defined yet?

If you tell us this, and claim that this is acceptable treatment of the 
20-40.000 characters not in the tables, we can at least discuss this 
proposal (whether such a partial TC/SC mapping is acceptable), instead of 
asking again and again what to do about them.

But it is impossible to implement an algorithm which says "this part will 
be worked out later".
