Gets the character (as a single-code-unit String) at the given index
.
The returned string represents exactly one UTF-16 code unit, which may be half of a surrogate pair. A single member of a surrogate pair is an invalid UTF-16 string:
var clef = '\u{1D11E}'; // These represent invalid UTF-16 strings. clef[0].codeUnits; // [0xD834] clef[1].codeUnits; // [0xDD1E]
This method is equivalent to new String.fromCharCode(this.codeUnitAt(index))
.
