Opt Subject: PRI #431 (UAX #42) feedback

I checked all known versions of the Unihan database, and I cannot find the
kWubi property that is documented in Section 4.4.23, Unihan properties, of
UAX #42 as follows:

code-point-attributes &= attribute kWubi
     { text }?

This property is also not mentioned in UAX #38.

Unless someone can find a version of the Unihan database that includes this
particular property, I recommend that its entry be dropped from UAX #42.

The following information is relevant to my recommendation that the kWubi
property be dropped from Section 4.4.23 of UAX #42:

1) The proposal that included the kWubi property was L2/06-208:

https://www.unicode.org/L2/L2006/06208-unihan-new-fields.pdf

2) This proposal was discussed during UTC #107 and reflected in the minutes:

https://www.unicode.org/consortium/utc-minutes/UTC-107-200605.html

The following are the relevant Consensus and Action Items:

>From 2006-05-18:

Properties - New Unihan Fields (B.14.6)

[107-C25] Consensus: Add kFourCornerCode and kWubi to Unihan.txt as
provisional properties for Unicode 5.0, subject to clear title to the
data. [L2/06-206]

[107-A57] Action Item for Deborah Goldsmith: Investigate the title and
licensing questions about kWubi and kFourCornerCode data for Unihan.txt,
and report to the Unicode officers by May 25th, 2006.

Note: see also 107-A68, 107-A69, and 107-A70 regarding kWubi data. Action
107-A57 was done, and reported back later in the meeting resulting in
removal of kWubi data from the release.

>From 2006-05-19:

Properties - Unihan (B.14.6)

[107-A68] Action Item for John Jenkins: Remove kWubi from the Unihan
database beta and generate a revision of Unihan.txt for the Unicode 5.0.
[L2/06-208]

[107-A69] Action Item for John Jenkins, Richard Cook: Remove references to
kWubi from Unicode Technical Report #38: A User's Guide to the Unihan
Database.

[107-A70] Action Item for Ken Whistler: Make relevant updates to the Unicode
5.0 text to remove references to kWubi data.

In other words, the kWubi property was never added to a released version of
the Unihan database, and should therefore be removed from Section 4.4.23 of
UAX #42.
