/**

* <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.
- * <blockquote>
+ * \htmlonly<blockquote>\endhtmlonly
* <pre>
* \code
* newLanguage
* newLanguage + newCountry + newVariant
* \endcode
* </pre>
- * </blockquote>
+ * \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.
* that you can use to specify the commonly used
* locales. For example, the following refers to a locale
* for the United States:
- * <blockquote>
+ * \htmlonly<blockquote>\endhtmlonly
* <pre>
* \code
* ULOC_US
* \endcode
* </pre>
- * </blockquote>
+ * \htmlonly</blockquote>\endhtmlonly
*
* <P>
* Once you've specified a locale you can query it for information about
* operations. For example, the <code>unum_xxx</code> functions format
* numbers, currency, or percentages in a locale-sensitive manner.
* </P>
- * <blockquote>
+ * \htmlonly<blockquote>\endhtmlonly
* <pre>
* \code
* UErrorCode success = U_ZERO_ERROR;
* unum_close(nf);
* \endcode
* </pre>
- * </blockquote>
+ * \htmlonly</blockquote>\endhtmlonly
* Each of these methods has two variants; one with an explicit locale
* and one without; the latter using the default locale.
- * <blockquote>
+ * \htmlonly<blockquote>\endhtmlonly
* <pre>
* \code
*
* unum_close(nf);
* \endcode
* </pre>
- * </blockquote>
+ * \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.
* For example, you can create a menu of all the collation objects
* suitable for a given language. Such classes implement these
* three class methods:
- * <blockquote>
+ * \htmlonly<blockquote>\endhtmlonly
* <pre>
* \code
* const char* uloc_getAvailable(int32_t index);
*
* \endcode
* </pre>
- * </blockquote>
+ * \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
+ * 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
+ * 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
* 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.
+ * don't use de-de\@EURO as an argument to resourcebundle.
