Slashed Zero

I find it really interesting that CSS (and common fonts) now includes font-variant-numeric: slashed-zero; as a standard option. I mean, there are many variations of ways of writing many typical characters (and I just mean in English, I’m sure it’s even more diverse when talking about multiple languages). I really like how the Andika font offers tons of character options so that it’s possible to make text for language learners that looks the way that one is teaching them to make their letters. But it’s only zero that has widespread support for two options (with or without a slash) with a dedicated CSS option for it (as opposed to the more generic font-variant choices) for picking whether one really wants a slash in their zero digits.
