 * \brief C API: Unicode case mapping functions using a UCaseMap service object.
 *
 * The service object takes care of memory allocations, data loading, and setup
 * for the attributes, as usual.
 *
 * Currently, the functionality provided here does not overlap with uchar.h
 * and ustring.h, except for ucasemap_toTitle().
 *
 * ucasemap_utf8XYZ() functions operate directly on UTF-8 strings.
