You've entirely missed the point I was trying to raise, Philippe.
It was not the ability to do private normalization of private use
characters that I was calling for, but making it easy to do.
Private Variation Selectors and Private Combining Marks
with a non-zero combining class that have appropriate
default properties are not necessary to enable normalization
according to a private use version of Unicode. However,
they do make such private normalizations easier to achieve,
as they are not dependent upon the private use agreement
changing the defaults of properties that affect normalization.
Besides, I don't think we want to encourage having font-based
overrides of the properties that affect normalization. That could
would raise all sorts of potential security holes unless such
changes were both restricted to only the PUA and PUA
characters were not allowed in secure applications. (The
latter may well be good idea unless the private use that
is desired specifically calls for such characters.)
