Re: Proposal: `String.prototype.codePointCount`

Consider a language such as Kannada, spoken in sourthern India, and the 25th most widely spoken language in the world, with 60M speakers. "Characters" in the written language are represented in Unicode as elements (sometimes called "letters") which are then composed at the rendering level to
