May somebody clarify that Unicode data is free? PD or
CC-BY-SA
compatible.
Sure. The license __for data and software__ is
http://unicode.org/copyright.html#Exhibit1 which is a BSD 3-clause
license with trivial changes to make it even clearer and freer, such as
the removal of the term "binary form" and "other materials".
CLDR data is embedded in most free software, e.g. via ICU, packages for
which are available e.g. in Debian which is notoriously restrictive as
regards licenses.
https://packages.debian.org/search?keywords=icu
Besides, language names are evidently not copyrightable and Unicode
makes no attempt to state the contrary. (Their license is still useful
for sad places like EU where the set of names could be considered
subject to sui generis database rights.)
