[ruby-core:74114] [Ruby trunk Bug#11844] Please update unicode-licensed files (license issue)

[ch---bugs-ruby-lang@zeha.at]

Issue #11844 has been updated by Christian Hofstaedtler.


The non-free problem is with this line: "supplied in this file in the creation of products supporting the Unicode Standard" - which implies that you can't use this file to produce stuff not supporting / not complying with "the Unicode Standard" (which itself may change at any time). (This is a problem for redistributors that may opt to use the GPL for Ruby and also causes DFSG issues.)

That's one of the reasons the Unicode default copyright text has changed multiple times in the past (current version: http://unicode.org/copyright.html). But it's not clear if the new copyright applies to files carrying the old header. Given that Unicode, Inc has made available (some) new files, with the exact same data, but with the new copyright info, it's being assumed that one can't just take the old files and slap the new header onto them.

Bug #11844: Please update unicode-licensed files (license issue)
https://bugs.ruby-lang.org/issues/11844#change-57261

* Author: Christian Hofstaedtler
* Status: Feedback
* Priority: Normal
* Assignee: 
* ruby -v: 2.2.3
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
Various files in enc/trans are old copies of Unicode.org files that forbid (re-)distribution. AFAICT, Unicode, Inc. has published newer versions of these files to fix this issue.
New versions could possibly be found on http://www.unicode.org/Public/MAPPINGS/OBSOLETE/EASTASIA/JIS/ and elsewhere under http://www.unicode.org/Public/

ext/json/generator/generator.c also has a restrictive Unicode, Inc. license blurb. Please fix this as well.
