 * \brief C API: Unicode string handling functions
 *
 * These C API functions provide general Unicode string handling.
 *
 * Some functions are equivalent in name, signature, and behavior to the ANSI C <string.h>
 * functions. (For example, they do not check for bad arguments like NULL string pointers.)
 * In some cases, only the thread-safe variant of such a function is implemented here
 * (see u_strtok_r()).
 *
 * Other functions provide more Unicode-specific functionality like locale-specific
 * upper/lower-casing and string comparison in code point order.
 *
 * ICU uses 16-bit Unicode (UTF-16) in the form of arrays of UChar code units.
 * UTF-16 encodes each Unicode code point with either one or two UChar code units.
 * (This is the default form of Unicode, and a forward-compatible extension of the original,
 * fixed-width form that was known as UCS-2. UTF-16 superseded UCS-2 with Unicode 2.0
 * in 1996.)
 *
 * Some APIs accept a 32-bit UChar32 value for a single code point.
 *
 * ICU also handles 16-bit Unicode text with unpaired surrogates.
 * Such text is not well-formed UTF-16.
 * Code-point-related functions treat unpaired surrogates as surrogate code points,
 * i.e., as separate units.
 *
 * Although UTF-16 is a variable-width encoding form (like some legacy multi-byte encodings),
 * it is much more efficient even for random access because the code unit values
 * for single-unit characters vs. lead units vs. trail units are completely disjoint.
 * This means that it is easy to determine character (code point) boundaries from
 * random offsets in the string.
 *
 * Unicode (UTF-16) string processing is optimized for the single-unit case.
 * Although it is important to support supplementary characters
 * (which use pairs of lead/trail code units called "surrogates"),
 * their occurrence is rare. Almost all characters in modern use require only
 * a single UChar code unit (i.e., their code point values are <=0xffff).
 *
 * For more details see the User Guide Strings chapter (https://unicode-org.github.io/icu/userguide/strings/).
 * For a discussion of the handling of unpaired surrogates see also
 * Jitterbug 2145 and its icu mailing list proposal on 2002-sep-18.

 * This function is intended for use in environments where UTF-8 text is

 *
 * Its semantics are:
 * - Well-formed UTF-8 text is correctly converted to well-formed UTF-16 text.
 * - The function will not read beyond the input string, nor write beyond
 *   the destCapacity.
 * - Malformed UTF-8 results in "garbage" 16-bit Unicode strings which may not
 *   be well-formed UTF-16.
 *   The function will resynchronize to valid code point boundaries
 *   within a small number of code points after an illegal sequence.
 * - Non-shortest forms are not detected and will result in "spoofing" output.
 *
 * For further performance improvement, if srcLength is given (>=0),
