使用 Ncurses (C++) 时不打印宽字符
Wide Characters not printing while using Ncurses (C++)
下面的代码无法打印宽字符：
#include <ncurses.h>
using namespace std;
int main(void){
initscr();
printw("█");
getch();
endwin();
}
虽然所有库都已正确安装，但此代码似乎在某些计算机上有效，而在其他计算机上无效。
（终端可以显示扩展字符！）
我编译这个使用：
g++ -std=c++14 widechartest.cpp -o widechar -lncursesw
有人可以告诉我问题出在哪里吗？
谢谢 8)
您没有初始化语言环境。 manual page 指出了这一点：
The library uses the locale which the calling program has initialized.
That is normally done with setlocale:
setlocale(LC_ALL, "");
If the locale is not initialized, the library assumes that characters
are printable as in ISO-8859-1, to work with certain legacy programs.
You should initialize the locale and not rely on specific details of
the library when the locale has not been setup.
