Thanks, I forgot to check this file, which was introduced later to allow
applications certified to comply to a particular version to be used with
later versions (for example to allow emulation of previous versions using
default character properties and absence of decompositions or case mappings
with non compliant texts that were encoded with unassigned code points).
As I don't need support for non compliant texts, I simply dropped this
reference. If this text file is really normative, then it means that texts
using unassigned code points should be rejected in compliant applications
and not accepted silently, not even by using default properties, which may
break in a later version of Unicode...
You also use the term "designated", isn't it also saying that it is
"assigned" (for example codepoints are assigned to surrogates, even if they
are not characters, and the FAQ already states that not all assigned code
points are characters.
