Milestone:  To Be Determined  |   Component:  locale 
  Version:  Boost 1.53.0      |    Severity:  Problem

 boost::locale::generator gen;
 gen.use_ansi_encoding(true);
 strLocaleName = std::use_facet<boost::locale::info>( gen("")).name();
 gen.use_ansi_encoding(false);
 strLocaleName = std::use_facet<boost::locale::info>( gen("")).name();

 strLocaleName always "zh_CN.UTF-8",
 why i can't get "zh_CN.GB2312" ?
 I want to convert wstring to string.Milestone
 But
 string = boost::locale::conv::from_utf(wstring, gen(""));
 is same with
 string = boost::locale::conv::from_utf(wstring, gen("UTF-8"));
 so it gives the unexpected result.


 And why get_system_locale give the expected result ?
 get_system_locale(true);  // "zh_CN.UTF-8"
 get_system_locale(false); // "zh_CN.windows-936"

 So I have to use this code,
 boost::locale::generator gen;
 strCodePage = boost::locale::util::get_system_locale();
 string      = boost::locale::conv::from_utf( wstring,
         std::use_facet<boost::locale::info>(gen(strCodePage)).encoding());

 Is this a bug of boost::locale::generator::use_ansi_encoding ?
