Duplicate content penalties are enforced to reduce the amount of useless content on the web and having redundant results in SERPs. Translating content into a different language is neither useless nor redundant. Someone who can't read English but reads Turkish won't be able to consume an English article. So it makes no sense for Google to discourage the translation of articles to other languages.
If translations were treated as duplicates, you'd have to use a canonical
tag, and that would cause only the canonical version (usually) to be displayed in SERPs. That means the other language versions would be inaccessible to search users. This is why if you have different localizations of the same content, you don't use canonical
to link them, you use the rel="translation"
attribute and link them together by a hyperlink (link
or a
).
