How should we deal with non-English content?
(unaccompanied by English translation)
The Over-Meta has this canonical.
We require English on Stack Overflow. See this list for Stack Overflow sites in languages other than English.
Questions written in non-English should be closed/flagged as unclear what you're asking.
Answers written in non-English should be flagged as very low quality, although not an answer will also work.
Comments written in non-English should be flagged as no longer needed.
Please do not translate questions for the original poster. They need to be able to respond to feedback, and if they cannot themselves >translate a question we cannot be certain that they can understand any feedback >provided (by comments, answers, or Help Center content).
The Mathematics SE Meta discussion is here. I was unable to find a CrossValidated Meta on this except for the usual "be respectful" discussions. I found nothing from Computational Science or Data Science SE Metas.
I think the StackOverflow model is a good one, especially given the breadth of Operations Research as a field and discipline. For reference it seems "American" English is the current prevailing preference for our tags from this Meta post.
I'll withhold further comments for now. What do you think?
