Is there a kotlinfied `Character.getNumericValue()`?

No, `getNumericValue` returns `5` for `"5"`

I don't think there is a Kotlin-only version, as it requires large character data tables. These are present in the JDK, but Javascript for example doesn't have an API for it.

You could do `char.toString().toInt()`, though it's not optimal.

And that also does not cover everything that `getNumericValue` does. `getNumericValue('Ⅱ')` ("Roman Numeral Two") returns `2`.

Ah, I was not aware of that. That is a weird function.

Yeah there are lots of these functions in the `Character` class, but I wonder what the purpose is? Is there ever a site where you can type in digits and where Ⅱ is allowed?

Presumably if your code is going to be used in a language with a different number system you'll be using specific input forms for those symbols?

That's the JDK for you.
You could argue that `java.time` is similarly overengineered with it's support for crazy calendar systems
