Most of the time it’s appropriate when an auto-correct feature turns single and double hash marks into single and double curly quotes. However, there are times when the curly quotes are awkward for some reason or actively wrong. For instance, hash marks indicate feet and inches, as in 5′ 6″. You could attempt to disable the auto-correct feature or copy and paste a hash mark from some other place but the simple fix is to type the hash mark, watch auto-correct change it and immediately press Command-Z to revert to the hash mark. We can’t guarantee this will work in all situations but it’s generally effective.
