The license for Unihan v1.1

Hello,

I would like to ask you about the license of the old version Unicode mapping data v1.1.

I am developing for Ruby package.
And there are files in the Ruby package with Unihan GB12345-90 (GB12345-80), GB2312-80 Unicode version 1.1. [1][2]
I would like to ask which license should be used for these files.

When I checked latest version Unihan.zip [3] of the Unicode mapping, and the ReadMe.txt [4], I found "Unicode Character Database (UCD)" was used.
However I checked the directory in version 1.1. [1], it seems that Unihan data has been disappeared from the web site directory. [5]
It seems that "Unicode license" had been used for that.

So, do you have any idea about which license I should use?

Thanks.
