Description

ISO-2022-KR and ISCII91 are no longer supported by Ruby. These encodings should be removed from Setting::ENCODINGS constant.

Iconv library used in Redmine 2.6 and earlier supported these two encodings, but String#encode used in Redmine 3.0 and later does not.

This is not correct. Redmine from 2.3 to 2.6 uses Iconv only when it runs on Ruby 1.8 (see source:tags/2.6.10/lib/redmine/codeset_util.rb#L1).

Redmine version Ruby version uses Iconv?
< 2.3 - yes
2.3 to 2.6 1.8 yes
2.3 to 2.6 >= 1.9 no
>= 3.0 - no

So, ISO-2022-KR and ISCII91 are available only when all of the following conditions are met.

  • Redmine version is 2.6.x or earlier
  • Ruby version is 1.8.x or earlier
