What to do when whitespace and capitalization either matter or don't matter in "includes" case?

[nottheswimmer]

It seems like a common use case for it to either be important or unimportant if an answer has specific capitalization or whitespace included. If there are multiple viable options, is the best choice available to just include all reasonable permutations as ideal answers? That's what I did with #106

I see that fuzzy_match would be viable for this in some cases but not in the case of math where the punctuation cannot be stripped out.
