-/**
- * UnicodeString is a string class that stores Unicode characters directly and provides
- * similar functionality as the Java String and StringBuffer classes.
- * It is a concrete implementation of the abstract class Replaceable (for transliteration).
- *
- * The UnicodeString class is not suitable for subclassing.
- *
- * <p>For an overview of Unicode strings in C and C++ see the
- * <a href="http://icu-project.org/userguide/strings.html">User Guide Strings chapter</a>.</p>
- *
- * <p>In ICU, a Unicode string consists of 16-bit Unicode <em>code units</em>.
- * A Unicode character may be stored with either one code unit
- * (the most common case) or with a matched pair of special code units
- * ("surrogates"). The data type for code units is UChar. 
- * For single-character handling, a Unicode character code <em>point</em> is a value
- * in the range 0..0x10ffff. ICU uses the UChar32 type for code points.</p>
- *
- * <p>Indexes and offsets into and lengths of strings always count code units, not code points.
- * This is the same as with multi-byte char* strings in traditional string handling.
- * Operations on partial strings typically do not test for code point boundaries.
- * If necessary, the user needs to take care of such boundaries by testing for the code unit
- * values or by using functions like
- * UnicodeString::getChar32Start() and UnicodeString::getChar32Limit()
- * (or, in C, the equivalent macros U16_SET_CP_START() and U16_SET_CP_LIMIT(), see utf.h).</p>
- *
- * UnicodeString methods are more lenient with regard to input parameter values
- * than other ICU APIs. In particular:
- * - If indexes are out of bounds for a UnicodeString object
- *   (<0 or >length()) then they are "pinned" to the nearest boundary.
- * - If primitive string pointer values (e.g., const UChar * or char *)
- *   for input strings are NULL, then those input string parameters are treated
- *   as if they pointed to an empty string.
- *   However, this is <em>not</em> the case for char * parameters for charset names
- *   or other IDs.
- * - Most UnicodeString methods do not take a UErrorCode parameter because
- *   there are usually very few opportunities for failure other than a shortage
- *   of memory, error codes in low-level C++ string methods would be inconvenient,
- *   and the error code as the last parameter (ICU convention) would prevent
- *   the use of default parameter values.
- *   Instead, such methods set the UnicodeString into a "bogus" state
- *   (see isBogus()) if an error occurs.
- *
- * In string comparisons, two UnicodeString objects that are both "bogus"
- * compare equal (to be transitive and prevent endless loops in sorting),
- * and a "bogus" string compares less than any non-"bogus" one.
- *
- * Const UnicodeString methods are thread-safe. Multiple threads can use
- * const methods on the same UnicodeString object simultaneously,
- * but non-const methods must not be called concurrently (in multiple threads)
- * with any other (const or non-const) methods.
- *
- * Similarly, const UnicodeString & parameters are thread-safe.
- * One object may be passed in as such a parameter concurrently in multiple threads.
- * This includes the const UnicodeString & parameters for
- * copy construction, assignment, and cloning.
- *
- * <p>UnicodeString uses several storage methods.
- * String contents can be stored inside the UnicodeString object itself,
- * in an allocated and shared buffer, or in an outside buffer that is "aliased".
- * Most of this is done transparently, but careful aliasing in particular provides
- * significant performance improvements.
- * Also, the internal buffer is accessible via special functions.
- * For details see the
- * <a href="http://icu-project.org/userguide/strings.html">User Guide Strings chapter</a>.</p>
