  * \brief C++ API: Locale ID object.

  */

 /**

  * A <code>Locale</code> object represents a specific geographical, political,

  * or cultural region. An operation that requires a <code>Locale</code> to perform

  * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>

  * to tailor information for the user. For example, displaying a number

  * is a locale-sensitive operation--the number should be formatted

  * according to the customs/conventions of the user's native country,

  * region, or culture.

  *

  * The Locale class is not suitable for subclassing.

  *

  * <P>

  * You can create a <code>Locale</code> object using the constructor in

  * this class:

  * \htmlonly<blockquote>\endhtmlonly

  * <pre>

  * .      Locale( const   char*  language,

  * .              const   char*  country,

  * .              const   char*  variant);

  * </pre>

  * \htmlonly</blockquote>\endhtmlonly

  * The first argument to the constructors is a valid <STRONG>ISO

  * Language Code.</STRONG> These codes are the lower-case two-letter

  * codes as defined by ISO-639.

  * You can find a full list of these codes at:

  * <BR><a href ="http://www.loc.gov/standards/iso639-2/">

  * http://www.loc.gov/standards/iso639-2/</a>

  *

  * <P>

  * The second argument to the constructors is a valid <STRONG>ISO Country

  * Code.</STRONG> These codes are the upper-case two-letter codes

  * as defined by ISO-3166.

  * You can find a full list of these codes at a number of sites, such as:

  * <BR><a href="http://www.iso.ch/iso/en/prods-services/iso3166ma/index.html">

  * http://www.iso.ch/iso/en/prods-services/iso3166ma/index.html</a>

  *

  * <P>

  * The third constructor requires a third argument--the <STRONG>Variant.</STRONG>

  * The Variant codes are vendor and browser-specific.

  * For example, use REVISED for a langauge's revised script orthography, and POSIX for POSIX.

  * Where there are two variants, separate them with an underscore, and

  * put the most important one first. For

  * example, a Traditional Spanish collation might be referenced, with

  * "ES", "ES", "Traditional_POSIX".

  *

  * <P>

  * Because a <code>Locale</code> object is just an identifier for a region,

  * no validity check is performed when you construct a <code>Locale</code>.

  * If you want to see whether particular resources are available for the

  * <code>Locale</code> you construct, you must query those resources. For

  * example, ask the <code>NumberFormat</code> for the locales it supports

  * using its <code>getAvailableLocales</code> method.

  * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular

  * locale, you get back the best available match, not necessarily

  * precisely what you asked for. For more information, look at

  * <code>ResourceBundle</code>.

  *

  * <P>

  * The <code>Locale</code> class provides a number of convenient constants

  * that you can use to create <code>Locale</code> objects for commonly used

  * locales. For example, the following refers to a <code>Locale</code> object

  * for the United States:

  * \htmlonly<blockquote>\endhtmlonly

  * <pre>

  *       Locale::getUS()

  * </pre>

  * \htmlonly</blockquote>\endhtmlonly

  *

  * <P>

  * Once you've created a <code>Locale</code> you can query it for information about

  * itself. Use <code>getCountry</code> to get the ISO Country Code and

  * <code>getLanguage</code> to get the ISO Language Code. You can

  * use <code>getDisplayCountry</code> to get the

  * name of the country suitable for displaying to the user. Similarly,

  * you can use <code>getDisplayLanguage</code> to get the name of

  * the language suitable for displaying to the user. Interestingly,

  * the <code>getDisplayXXX</code> methods are themselves locale-sensitive

  * and have two versions: one that uses the default locale and one

  * that takes a locale as an argument and displays the name or country in

  * a language appropriate to that locale.

  *

  * <P>

  * ICU provides a number of classes that perform locale-sensitive

  * operations. For example, the <code>NumberFormat</code> class formats

  * numbers, currency, or percentages in a locale-sensitive manner. Classes

  * such as <code>NumberFormat</code> have a number of convenience methods

  * for creating a default object of that type. For example, the

  * <code>NumberFormat</code> class provides these three convenience methods

  * for creating a default <code>NumberFormat</code> object:

  * \htmlonly<blockquote>\endhtmlonly

  * <pre>

  *     UErrorCode success = U_ZERO_ERROR;

  *     Locale myLocale;

  *     NumberFormat *nf;

  *

  *     nf = NumberFormat::createInstance( success );          delete nf;

  *     nf = NumberFormat::createCurrencyInstance( success );  delete nf;

  *     nf = NumberFormat::createPercentInstance( success );   delete nf;

  * </pre>

  * \htmlonly</blockquote>\endhtmlonly

  * Each of these methods has two variants; one with an explicit locale

  * and one without; the latter using the default locale.

  * \htmlonly<blockquote>\endhtmlonly

  * <pre>

  *     nf = NumberFormat::createInstance( myLocale, success );          delete nf;

  *     nf = NumberFormat::createCurrencyInstance( myLocale, success );  delete nf;

  *     nf = NumberFormat::createPercentInstance( myLocale, success );   delete nf;

  * </pre>

  * \htmlonly</blockquote>\endhtmlonly

  * A <code>Locale</code> is the mechanism for identifying the kind of object

  * (<code>NumberFormat</code>) that you would like to get. The locale is

  * <STRONG>just</STRONG> a mechanism for identifying objects,

  * <STRONG>not</STRONG> a container for the objects themselves.

  *

  * <P>

  * Each class that performs locale-sensitive operations allows you

  * to get all the available objects of that type. You can sift

  * through these objects by language, country, or variant,

  * and use the display names to present a menu to the user.

  * For example, you can create a menu of all the collation objects

  * suitable for a given language. Such classes implement these

  * three class methods:

  * \htmlonly<blockquote>\endhtmlonly

  * <pre>

  *       static Locale* getAvailableLocales(int32_t& numLocales)

  *       static UnicodeString& getDisplayName(const Locale&  objectLocale,

  *                                            const Locale&  displayLocale,

  *                                            UnicodeString& displayName)

  *       static UnicodeString& getDisplayName(const Locale&  objectLocale,

  *                                            UnicodeString& displayName)

  * </pre>

  * \htmlonly</blockquote>\endhtmlonly
