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.

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

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
