The specification actually called only for Latin, Greek, and Cyrillic;
I added Hebrew pour la lagniappe. If someone wants to add Arabic, I
encourage them to do so.

True; however, the current list indicates the scope of what actually
happens, even if it is overlong.

I believe that all Mn-class characters, and only they, are deleted by this.

I don't think that matters. Long historical practice has made SHCHA a
separate letter, just as G, J, U, and W are now separate Latin letters
from C, I, V, and VV-ligature.

I think I agree with this: i-breve does not have the same universal status as
