Yes, I saw the Swiss apostrophes in the Wikipedia article that question links to (https://en.wikipedia.org/wiki/Decimal_separator#Examples_of_...), but there are no backticks mentioned there (hence my question). The only times I've seen backticks or grave accents used in place of apostrophes, it's been done consistently (I'm guessing some keyboard layouts don't have apostrophes?), while orangepanda used an apostrophe too, as if the backticks were a deliberate choice.
