In plain Java I really miss a few of the ICU4J routines, like:

    * char c1 = UTF16.getLeadSurrogate(codePoint);
    * char c2 = UTF16.getLeadSurrogate(codePoint);
    * String s = UTF16.valueOf(codePoint);

You can do them in plain Java, as in the above expression, but they're awkward and not as clear to read. And instead of the third one, the best I see in plain Java is the following, which is really pretty ugly (is there any better way?).


String s = new StringBuilder().appendCodePoint(codePoint).toString();
