RE: Unicode education in Schools

IIUC the limitation seems to be only that functions such as "charAt" do not recognize that surrogates aren't valid characters: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/charAt via https://stackoverflow.com/a/8716157/1503120. This is a problem of many

Re: Unicode education in Schools

Because there are many systems that can now handle BMP characters but not cannot handle SMP characters. One example being systems that use mysql utf8 (3 byte encoding) and have not yet updated to utf8mb4 (4 byte encoding) So, I consider it important to familiarise students with SMP characters
