Comment (by anonymous):

 Sorry, the format is chaos.
 Follow is the right format:


 void f()

 {

 boost::locale::generator     gen;

 std::string                        strLocaleName;




 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.

 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 ?
