Patch #34750
Updated by Go MAEDA about 3 years ago
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.
