Based on a quick look, these files establish a correspondence between
different character set encodings.  Copyright protects creative
expression.  What is the creative part of this mapping?  I can see two
possible bases: character selection and ambiguity resolution.

Character selection would be the selection of which characters to list
(or not list) in each file.  Ambiguity resolution would be the
handling of look-alike characters in distinct sets.

Neither of those seem like they are actually creative, given how
thoroughly standardized and documented the character set encodings
are.

That being said, I am not sure enough to risk it in court on my dime.
I would hope that Adobe would be willing to provide the data with a
DFSG-compatible license and/or a notice that makes it clear whether
they think the mappings are protected by copyright.
