/**
 * Base class for objects to which Unicode characters and strings can be appended.
 * Combines elements of Java Appendable and ICU4C ByteSink.
 *
 * This class can be used in APIs where it does not matter whether the actual destination is
 * a UnicodeString, a char16_t[] array, a UnicodeSet, or any other object
 * that receives and processes characters and/or strings.
 *
 * Implementation classes must implement at least appendCodeUnit(char16_t).
 * The base class provides default implementations for the other methods.
 *
 * The methods do not take UErrorCode parameters.

     *  int32_t capacity;
     *  char16_t* buffer = app.getAppendBuffer(..., &capacity);

     * the desiredCapacityHint if appropriate.
     * If a caller cannot provide a reasonable guess at the desired capacity,
     * it should pass desiredCapacityHint=0.
     *
     * If a non-scratch buffer is returned, the caller may only pass
     * a prefix to it to appendString().
     * That is, it is not correct to pass an interior pointer to appendString().
