Boost C++ Libraries: Ticket #8570: boost::locale::generator::use_ansi_encoding bug: gives the unexpected result on Win7 Chinese.

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 ?

What backends are compiled in? Does ICU compiled in? Does std backend compiled in? What compiler?

Note: winapi backend (which is default on windows if ICU is not present) does not support ANSI encoding. So you need to specify std backend explicitly or use ICU.

Thanks, I was complied in VS2010,and not use ICU. But follow ways not to specify std backend explicitly. Only to use locale("");

setlocale(LC_CTYPE,"");
wcstombs(string, wstring, _MAX_FNAME);

std::locale sys_locale("");
std::use_facet<std::codecvt<wchar_t,char, mbstate_t> >(sys_locale).out(...);
