I was looking for something, but all I can find is either loose about
surrogates (e.g., Java
<https://docs.oracle.com/javase/specs/jls/se7/html/jls-3.html>), or deals
in code points rather than UTF-16 code units.
Can you say why you want/need strict 16-bit escapes for well-formed UTF-16
code units, rather than what others are doing?
