ECMAScript string values are a finite ordered sequence of zero or more 16-bit unsigned integer values. However, ECMAScript does not place any restrictions or requirements on the integer values except that they must be 16-bit unsigned integers. In well-formed strings, each integer value in the sequence represents a single 16-bit code unit of UTF-16-encoded Unicode text. However, not all sequences o

My avoidance continued until I faced a problem that required detailed Unicode knowledge. There was no way to apply situational solutions. After putting in some eff
