如何使用ncurses在不同的终端上以相同的方式呈现Unicode？

Question

我被告知使用ncurses在this帖子中由用户MGetz在我的程序中呈现unicode级别。所以，我已经更新了我的代码以使用ncurses，但它在不同的终端中仍然呈现不同的方式。我使用g++ file.cpp -o file -std=c++11 -lncursesw编译了我的代码。说到我的代码，就在这里。

#include <iostream>
#include <string>
#include <ncurses.h>
#include <locale.h>

using namespace std;

void PrintLevel();

string lvl[9][11] {
        {"\u250f", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u2513"},
        {"\u2503", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u2503"},
        {"\u2503", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u2503"},
        {"\u2503", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u2503"},
        {"\u2503", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u2503"},
        {"\u2503", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u2503"},
        {"\u2503", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u2503"},
        {"\u2503", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u0020", "\u2503"},
        {"\u2517", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u2501", "\u251B"}
    };

int main() {
    setlocale(LC_ALL, "");
    initscr();
    PrintLevel();
    getch();
    endwin();
}

void PrintLevel() {
    for(int i = 0; i<9; i++) {
        for(int j = 0; j<11; j++) {
            printw(lvl[i][j].c_str());
            if(j == 10) {
                printw("\n");
            }
        }
    }

    refresh();
}

哦，仅供参考，我正在使用Codenvy，因为我只能访问我的学校Chromebook。尝试在另一个类似Codenvy的服务Codeanywhere上，Unicode甚至无法正确呈现，我明白了：

副手：

• 由于屏幕显示替换字符（那个奇怪的问号），人们会认为终端设置为UTF-8，但是
• 您正在呼叫setlocale使用区域设置，但不要提及它们的内容（LC_ALL等，如 locale所示命令）和
• 没有提及您是否正在使用 ncursesw （预期）或 ncurses 进行编译/链接。

如果您同时使用错误的区域设置并使用 ncurses 进行关联，则可能会显示该图片。
