+ * \brief C API: Locale |
+ * |
+ * <h2> ULoc C API for Locale </h2> |
+ * A <code>Locale</code> 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. In the C APIs, a locales is simply a const char string. |
+ * |
+ * <P> |
+ * You create a <code>Locale</code> with one of the three options listed below. |
+ * Each of the component is separated by '_' in the locale string. |
+ * \htmlonly<blockquote>\endhtmlonly |
+ * <pre> |
+ * \code |
+ * newLanguage |
+ * |
+ * newLanguage + newCountry |
+ * |
+ * newLanguage + newCountry + newVariant |
+ * \endcode |
+ * </pre> |
+ * \htmlonly</blockquote>\endhtmlonly |
+ * The first option 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 a number of sites, such as: |
+ * <BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt"> |
+ * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</a> |
+ * |
+ * <P> |
+ * The second option includes an additonal <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.chemie.fu-berlin.de/diverse/doc/ISO_3166.html"> |
+ * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</a> |
+ * |
+ * <P> |
+ * The third option requires another additonal information--the |
+ * <STRONG>Variant.</STRONG> |
+ * The Variant codes are vendor and browser-specific. |
+ * For example, use WIN for Windows, MAC for Macintosh, 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_WIN". |
+ * |
+ * <P> |
+ * Because a <code>Locale</code> is just an identifier for a region, |
+ * no validity check is performed when you specify a <code>Locale</code>. |
+ * If you want to see whether particular resources are available for the |
+ * <code>Locale</code> you asked for, you must query those resources. For |
+ * example, ask the <code>UNumberFormat</code> for the locales it supports |
+ * using its <code>getAvailable</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>UResourceBundle</code>. |
+ * |
+ * <P> |
+ * The <code>Locale</code> provides a number of convenient constants |
+ * that you can use to specify the commonly used |
+ * locales. For example, the following refers to a locale |
+ * for the United States: |
+ * \htmlonly<blockquote>\endhtmlonly |
+ * <pre> |
+ * \code |
+ * ULOC_US |
+ * \endcode |
+ * </pre> |
+ * \htmlonly</blockquote>\endhtmlonly |
+ * |
+ * <P> |
+ * Once you've specified a locale you can query it for information about |
+ * itself. Use <code>uloc_getCountry</code> to get the ISO Country Code and |
+ * <code>uloc_getLanguage</code> to get the ISO Language Code. You can |
+ * use <code>uloc_getDisplayCountry</code> to get the |
+ * name of the country suitable for displaying to the user. Similarly, |
+ * you can use <code>uloc_getDisplayLanguage</code> to get the name of |
+ * the language suitable for displaying to the user. Interestingly, |
+ * the <code>uloc_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> |
+ * The ICU provides a number of services that perform locale-sensitive |
+ * operations. For example, the <code>unum_xxx</code> functions format |
+ * numbers, currency, or percentages in a locale-sensitive manner. |
+ * </P> |
+ * \htmlonly<blockquote>\endhtmlonly |
+ * <pre> |
+ * \code |
+ * UErrorCode success = U_ZERO_ERROR; |
+ * UNumberFormat *nf; |
+ * const char* myLocale = "fr_FR"; |
+ * |
+ * nf = unum_open( UNUM_DEFAULT, NULL, success ); |
+ * unum_close(nf); |
+ * nf = unum_open( UNUM_CURRENCY, NULL, success ); |
+ * unum_close(nf); |
+ * nf = unum_open( UNUM_PERCENT, NULL, success ); |
+ * unum_close(nf); |
+ * \endcode |
+ * </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> |
+ * \code |
+ * |
+ * nf = unum_open( UNUM_DEFAULT, myLocale, success ); |
+ * unum_close(nf); |
+ * nf = unum_open( UNUM_CURRENCY, myLocale, success ); |
+ * unum_close(nf); |
+ * nf = unum_open( UNUM_PERCENT, myLocale, success ); |
+ * unum_close(nf); |
+ * \endcode |
+ * </pre> |
+ * \htmlonly</blockquote>\endhtmlonly |
+ * A <code>Locale</code> is the mechanism for identifying the kind of services |
+ * (<code>UNumberFormat</code>) that you would like to get. The locale is |
+ * <STRONG>just</STRONG> a mechanism for identifying these services. |
+ * |
+ * <P> |
+ * Each international serivce 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> |
+ * \code |
+ * const char* uloc_getAvailable(int32_t index); |
+ * int32_t uloc_countAvailable(); |
+ * int32_t |
+ * uloc_getDisplayName(const char* localeID, |
+ * const char* inLocaleID, |
+ * UChar* result, |
+ * int32_t maxResultSize, |
+ * UErrorCode* err); |
+ * |
+ * \endcode |
+ * </pre> |
+ * \htmlonly</blockquote>\endhtmlonly |
+ * <P> |
+ * Concerning POSIX/RFC1766 Locale IDs, |
+ * the getLanguage/getCountry/getVariant/getName functions do understand |
+ * the POSIX type form of language_COUNTRY.ENCODING\@VARIANT |
+ * and if there is not an ICU-stype variant, uloc_getVariant() for example |
+ * will return the one listed after the \@at sign. As well, the hyphen |
+ * "-" is recognized as a country/variant separator similarly to RFC1766. |
+ * So for example, "en-us" will be interpreted as en_US. |
+ * As a result, uloc_getName() is far from a no-op, and will have the |
+ * effect of converting POSIX/RFC1766 IDs into ICU form, although it does |
+ * NOT map any of the actual codes (i.e. russian->ru) in any way. |
+ * Applications should call uloc_getName() at the point where a locale ID |
+ * is coming from an external source (user entry, OS, web browser) |
+ * and pass the resulting string to other ICU functions. For example, |
+ * don't use de-de\@EURO as an argument to resourcebundle. |
