wcout用于不同的语言环境

问题描述

我以前曾经为Windows编写代码，现在试图使代码在Linux上工作.这是一个示例代码，我想问一个问题:

#include< iostream>

int main(int argc，char * argv []){
setlocale(LC_ALL，"be_BY.utf8");
const char * HelloWorld_char =Вітаю，шаноўныспадар！";
const wchar_t * HelloWorld_wchar_t = LВітаю，шаноўныспадар！";
std :: cout<< HelloWorld_char<< std :: endl;
std :: wcout<< HelloWorld_wchar_t<< std :: endl;
返回0;
}

源文件是UTF-8编码的.我用
编译
g ++ -fexec-charset = utf-8 -fwide-exec-charset = utf-8 test.cpp

使用cout的代码行有效(无论我用setlocale！?设置了什么语言环境).但是wcout会打印垃圾.你能解释为什么吗?是否可以对wcout进行本地化?谢谢

PS.好吧，这些字符串在我的页面上看起来不太好，但它们只包含"Hello，World！".

I used to code for Windows now I''m trying to make the code work for Linux. This is a sample code that I''d like to ask a question about:

#include <iostream>

int main (int argc, char * argv []) {
setlocale (LC_ALL, "be_BY.utf8");
const char * HelloWorld_char = "Вітаю, шаноўны спадар!";
const wchar_t * HelloWorld_wchar_t = L"Вітаю, шаноўны спадар!";
std::cout << HelloWorld_char << std::endl;
std::wcout << HelloWorld_wchar_t << std::endl;
return 0;
}

The source file is UTF-8 encoded. I compile it with

g++ -fexec-charset=utf-8 -fwide-exec-charset=utf-8 test.cpp

The line of code with cout works (no matter what locale I set with setlocale !?). But wcout prints rubbish. Can you explain why? Is it possible to localize wcout as well? Thanks

PS. Well, the strings don''t look nice on my page but they just contain "Hello, World!" text in Belarusian.

推荐答案

#include <locale>
#include <iostreams>
int main()
{
    std::locale loc("be_BY.utf8");
    std::cout.imbue(loc);
    std::wcout.imbue(loc);

    //Your writings goes here, remove the setlocale call
}
