The license for the files is seen in "EXHIBIT 1" in the following URL.

http://www.unicode.org/copyright.html

Roughly it claims that the copied files or software containing
the copy of thefiles should be accompanied by the same copyright
notice, or it should be seen in associated documentation. So we
could contain the files by adding some notice but fially we
decide not to contain them in the repository, I think

I'm not intending to insisnt on removing them if someone strongly
wants to preserve them, since their existence don't harm
anything.
