Is it correct to use “punctuation outside of the quotations”, or “inside?”

I've heard that you should always place ending punctuation inside of quotes, no matter what.

Are there any cases where it is appropriate for a sentence to end with ".?

Best Answer

Yes. See the Economist style guide:

If the quotation does not include any punctuation, the closing inverted commas should precede any punctuation marks that the sentence requires.
