I'm quoting a passage that includes a superscript indicating a footnote. I'm not quoting the footnote, however. What do I do? If I leave the superscript in, it's distracting, since it suggests that there's a footnote to be found in my paper--at the very least, the reader will probably wonder about that for a brief moment. If I delete the superscript but don't indicate that I've done so, I'm misrepresenting the original text. If I replace the superscript with an ellipsis, that would normally convey that there's more missing than a mere superscript.
(My apologies if this is a duplicate. It's impossible construct a search that would find an existing answer to this question.)
