Update LICENSE-UNICODE text #28
Conversation
I'm unsure where the LICENSE-UNICODE text in this repo originated, but it's fairly different from the [canonical text](https://spdx.org/licenses/Unicode-DFS-2016.html) in the SPDX license list, so this updates it to match. The reason for this change is that the Unicode-3.0 license was added recently, which can actually be a [closer match](EmbarkStudios/cargo-about#267) to the current text, resulting in the SPDX identifier mismatching the actual one this crate is licensed under.
There was a problem hiding this comment.
The original is from https://web.archive.org/web/20220118205616/https://www.unicode.org/license.txt. As far as I know, this is the canonical rendering of Unicode-DFS-2016, provided directly by Unicode. The LICENSE-UNICODE file in this repo is byte identical to that one. The Rust standard library also uses the same in https://github.com/rust-lang/rust/blob/1.82.0/COPYRIGHT#L346-L391.
I would prefer if this were fixed in SPDX.

According to archive.org, the content of https://unicode.org/license.txt was swapped out from "UNICODE, INC. LICENSE AGREEMENT - DATA FILES AND SOFTWARE" to "UNICODE LICENSE V3" between the dates 2023.06.03 and 2023.09.11, which means between Unicode 15.0.0 (2022.09.13) and Unicode 15.1.0 (2023.09.12). A license wording change is not mentioned in the 15.1.0 release summary or announcement post. But I guess we are intended to infer that data files from Unicode 15.1.0 should be specified as licensed Unicode-3.0 as opposed to Unicode-DFS-2016. |

Yah, that's unfortunate lack of/ambiguous communication on their end, I've updated the text/references to Unicode-3.0. |

I've sent a post regarding this issue to the "legal" mailing list for the Fedora Project. Red Hat lawyers are involved with SPDX upstream, maybe they can provide more insights: https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/thread/CHVW3EPLVQYH6SSVAOLOZJAVBXCGWOR5/ |
Unicode changed its license between versions 15.0.0 and 15.1.0, from Unicode-DFS-2016 to Unicode-3.0. dtolnay/unicode-ident#28

See dtolnay/unicode-ident#28. TL;DR: unicode-ident now requires the Unicode 3.0 license, so this commit updates deny.toml to allow this rather than Unicode-DFs-2016.
