In the accumulated feedback on PRI #411, David Corbett brings up some
characters new to Unicode 13.0 and mentions that their assigned
Identifier_Status appears incorrect. This is a valid bug report for most of
the character mentioned, but since Identifier_Status is derived from
Identifier_Type, it's their Identifier_Type that should be fixed instead.

Here are proposed Identifier_Types for the characters mentioned by Corbett:

0D04; Technical Obsolete
0D81; Technical
1ABF; Technical
1AC0; Technical
A7F5; Obsolete
A7F6; Obsolete
AB68; Technical

Note that contrary to Corbett's suggestion, no changes are proposed for
U+A7C7 and U+A7C8, since they are used in the modern orthography for the
Moro language of Sudan.
