there would seem to be several arguements to say data could be included;_
(1) data that is non-creative in nature can not be copyrighted as such
-- a table of Morohashi indexes to Unicode is non creative (accept for
the lines which are wrong! remove these and everyone is happy). This
is the most relevant point.
(2) GPL, general public license, is in many respects putting something
under public domain - if the phrasing of the terms for Unicode don't
allow for this, then unless we appy the non-creative rule (1). It may
well be hard in the future for Unihan.txt to be expanded. I suggest
the unicode rules should be revised to allow GPL data.
(3) with this data which anyone can download, the fact that it is
placed under GPL in such a way means that the "author" wishes the data
to be available and I can not see how they will object to either it
being placed in Unihan.txt and changing it (which is allowed under the
terms of GPL)
(4) If Unihan.txt does have this restrcition (see the above points
above which suggest it does not have), and does not change it, then in
the futuure it may well be outdone by a UnihanGPL.txt.
