Today I don't feel very creative, perhaps because deliberating inventing bad
ideas does not appeal too much to my creativeness. :-)

But perhaps I have some suggestions for the less creative part of the FAQ,
which is: listing the existing policies for excluding some classes of
proposals.

In my understanding, a few such policies are:

- No precomposed ligatures which can be encoded using a sequence of existing
character (possibly joined by ZWJ's);

- No precomposed "accented characters" which can be composed using an
existing character and one or more existing combining diacritics;

- No clones of existing characters whose sole purpose is making a *logical*
differentiation from some existing characters (e.g., hex digits looking
identical to existing characters "0..9" and "A...F"; or a symbol for "meter"
looking identical to Latin "m");

- No clones of existing characters whose sole purpose is making a
*graphical* differentiation from some existing characters (e.g., a Serbian
letter "t", disunified from Russian on the basis that italics looks
different in the two languages);

- No presentation glyphs for shapes that can already be obtained using
regular characters in conjunction with ZWJ or ZWNJ.
