I am trying to advocate vi.SE by going out on SO, answering Vim questions and then directing people towards us here on vi.SE. Yet, I encountered a situation in which a question on SO has no equivalent here on vi.SE.
I am aware of What do we do with questions that are already answered somewhere else on SE? But it would be rather difficult for me to beat my own answer.
Is it the correct action to make a better question and then extend my own answer as a self-answer to it?
The question I'm thinking of asking (and self-answering) is "How do I open files in exotic encodings in Vim?"
