| 68 | <div class="textblock"><p>The <code>std::locale::name</code> function provides very limited information about a locale. Such a name is platform- and compiler-dependent, and is useless for Boost.Locale. There is no way to change it, so for all locales created by Boost.Locale, <code>name()</code> returns the same value as <code>name()</code> for <code>std::locale::classic()</code>.</p> | |
| 69 | <p>Thus an additional facet was created, giving more precise information: <a class="el" href="classboost_1_1locale_1_1info.html" title="a facet that holds general information about locale ">boost::locale::info</a>. It has the following member functions:</p> | |
| 70 | <ul> | |
| 71 | <li><a class="el" href="classboost_1_1locale_1_1info.html#af8181bf226f369548c030220932323b9">std::string name()</a> – the full name of the locale, for example <code>en_US.UTF-8</code> </li> | |
| 72 | <li><a class="el" href="classboost_1_1locale_1_1info.html#a7c56b9df3aba82649afc66c06192c7df">std::string language()</a> – the ISO-639 language code of the current locale, for example "en".</li> | |
| 73 | <li><a class="el" href="classboost_1_1locale_1_1info.html#a249c20e36da6827a8dc8b12a8342a7dc">std::string country()</a> – the ISO-3199 country code of the current locale, for example "US".</li> | |
| 74 | <li><a class="el" href="classboost_1_1locale_1_1info.html#a2e949e4362c8f0195e2a645fe875f1b4">std::string variant()</a> – the variant of current locale, for example "euro".</li> | |
| 75 | <li><a class="el" href="classboost_1_1locale_1_1info.html#a1979a5d7b90604c45e856a139c68f5ba">std::string encoding()</a> – the encoding used for <code>char</code> based strings, for example "UTF-8"</li> | |
| 76 | <li><a class="el" href="classboost_1_1locale_1_1info.html#aafbbb5c291f60ce6fc3bc056859ba181">bool utf8()</a> – a fast way to check whether the encoding is UTF-8.</li> | |
| 77 | </ul> | |
| 78 | <p>For example:</p> | |
| 79 | <div class="fragment"><div class="line">cout << <span class="stringliteral">"The language code is "</span> << std::use_facet<boost::locale::info>(some_locale).language() << endl;</div> | |
