Please update my previous report on numeric value for U+F9B2
(via the web form) with the following more extensive report.
Or make the following into a separate UTC document.

===============================================

The following two characters are not given numeric values in
DerivedNumericValues.txt:

6F06; ?;    7        CJK UNIFIED IDEOGRAPH-6F06
jp-obsolete-financial
	(according to
http://en.wikipedia.org/wiki/Japanese_numerals#Formal_numbers)
9621; ?; 1000        CJK UNIFIED IDEOGRAPH-9621
jp-obsolete-financial
	(according to
http://en.wikipedia.org/wiki/Japanese_numerals#Formal_numbers)

Wikipedia gives numeric values (as above) to these two CJK characters. I
have no
independent confirmation though. Many other CJK characters already given
numeric
values are obsolete in the same way, so that in itself should be no
hindrance.



Wikipedia also gives very large (over one trillion) numeric values to
certain CJK
characters. At least some of these may be interesting to give numeric
values to in
DerivedNumericValues.txt, especially since some of them are also used as
translations
for SI prefixes. See
http://en.wikipedia.org/wiki/Chinese_numerals#SI_prefixes.

(Aside: I don't know where the CJK numeric values in
DerivenNumericValues.txt are
*derived* from.)


------------------------------------------


The following eight characters are each canonically equivalent with a
CJK character
that is given a numeric value in DerivedNumericValues.txt, but these
canonical
equivalents are not given any numeric value neither in UnicodeData.txt
nor in
DerivedNumericValues.txt. I think canonically equivalent strings should
carry
the same numeric values, not just informally but also formally in the
Unicode
database, so the following eight characters should be given appropriate
numeric
values in UnicodeData.txt and in DerivedNumericValues.txt.

F96B;CJK COMPATIBILITY IDEOGRAPH-F96B;Lo;0;L;53C3;;;;N;;;;;    3
F973;CJK COMPATIBILITY IDEOGRAPH-F973;Lo;0;L;62FE;;;;N;;;;;   10
F978;CJK COMPATIBILITY IDEOGRAPH-F978;Lo;0;L;5169;;;;N;;;;;    2
F9B2;CJK COMPATIBILITY IDEOGRAPH-F9B2;Lo;0;L;96F6;;;;N;;;;;    0
F9D1;CJK COMPATIBILITY IDEOGRAPH-F9D1;Lo;0;L;516D;;;;N;;;;;    6
F9D3;CJK COMPATIBILITY IDEOGRAPH-F9D3;Lo;0;L;9678;;;;N;;;;;    6
F9FD;CJK COMPATIBILITY IDEOGRAPH-F9FD;Lo;0;L;4EC0;;;;N;;;;;   10
2F890;CJK COMPATIBILITY IDEOGRAPH-2F890;Lo;0;L;5EFE;;;;N;;;;;  9


-------------------------------------


The CJK telegraph symbols should also be given numeric values in
UnicodeData.txt
as well as DerivedNumericValues.txt:
* for months (32C0-32CB, have compat decomps beginning with digits
ending with 6708):
		values 1-12
* for days (33E0-33FE, have compat decomps beginning with digits ending
with 65E5):
		values 1-31
* for hours (3358-3370, have compat decomps beginning with digits ending
with 70B9):
		values 0-24

Note that parenthesized/circled digits/numbers are given numeric values,
and these
telegraph symbols should not be handled in principle differently in that
regard.
