Most JavaScript engines use UTF-16 encoding, so let’s detail into UTF-16. UTF-16 (the long name: 16-bit Unicode Transformation Format) is a variable-length encoding: Code points from BMP are encoded using a single code unit of 16-bit. Code points from astral planes are encoded using two code units of 16-bit each.
