Stymied by the UnicodeĀ® stability policies again:

"The General_Category property values will not be further subdivided. "
"The General_Category property value Surrogate (Cs) is immutable: the
set of code points with that value will never change."

<http://unicode.org/policies/stability_policy.html#Property_Value>

Can anyone think of a way to extend UTF-16 without adding new
surrogates or inventing a new general category?
