[GNU-linux-libre] Nonfree Unicode files

[ag ag01]

Unicode, Inc. hereby grants the right to freely use the information supplied in 
this file in the creation of products supporting the Unicode Standard, and to 
make copies of this file in any form for internal or external distribution as 
long as this notice remains attached.

That is the copyright for several Unicode files. I previously mentioned map-* 
files in font-util that have this copyright and I recently found that some 
files in LLVM have this copyright notice. The file lib/support/ConvertUTF.c has 
this copyright notice. Above that copyright notice it says that it is 
distributed under the terms of in LICENSE.TXT. There is no LICENSE.TXT in that 
directory, although the one in the top directory is a free license. It seems 
quite a few files made by Unicode use this license.
