Hi Jerry,
I did a bit of digging and looks like this was added to the repo back in
2022 when we started the SPDX conversion.
That seems to suggest that it had been considered a "bad" license
previously, but I can't find a legacy record of that.
Reviewing the license now, it's a bit unclear to me as to what makes it
not-allowed. It states (edits on format, mine):
" 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."
The first part is a bit restrictive but the "and" and the second part
seems to help.
I believe Richard is OOO right now. Let me confer with him early next
week and one of us will get back to you!
Thanks,
Jilayne

I've been using scancode to take an in-depth look at packages I
maintain. I'm up to packages that start with "a"! While looking at
the antlr3 package, I found that it contains 3 files with the
LicenseRef-Unicode-legacy-source-code license, which is not allowed
for Fedora [1]. The files are part of the C/C++ backend. They have
been built into binary RPMs for Fedora since 2010 [2] (Fedora 12?).
Repoquery shows that nothing in Fedora uses the C/C++ backend. I will
build updates for F42, F43, and Rawhide that disable it. My question
is whether I need to do anything more than that. Do I need to scrub
the offending files out of the tarball, for example?

Is there anybody who can advise me on this? I assume this license is
not allowed in Fedora due to the Limitations clause at the end. Do I
need to scrub the sources, or is simply not building the code into the
binary RPMs sufficient?
