Stymied by the Unicode® 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?
