如何将 Unicode 字符写入控制台?

How to write Unicode characters to the console?(如何将 Unicode 字符写入控制台?)

问题描述

我想知道是否可以在控制台应用程序中使用 .NET 编写像 ℃ 这样的字符.当我尝试写这个字符时，控制台会输出一个问号.

I was wondering if it was possible, in a console application, to write characters like ℃ using .NET. When I try to write this character, the console outputs a question mark.

推荐答案

很可能您的输出编码设置为 ASCII.在发送输出之前尝试使用它:

It's likely that your output encoding is set to ASCII. Try using this before sending output:

Console.OutputEncoding = System.Text.Encoding.UTF8;

(MSDN 链接 到支持文件.)

这里有一个小控制台测试应用程序，您可能会觉得很方便:

And here's a little console test app you may find handy:

C#

using System;
using System.Text;

public static class ConsoleOutputTest {
    public static void Main() {
        Console.OutputEncoding = System.Text.Encoding.UTF8;
        for (var i = 0; i <= 1000; i++) {
            Console.Write(Strings.ChrW(i));
            if (i % 50 == 0) { // break every 50 chars
                Console.WriteLine();
            }
        }
        Console.ReadKey();
    }
}

VB.NET

imports Microsoft.VisualBasic
imports System

public module ConsoleOutputTest 
    Sub Main()
        Console.OutputEncoding = System.Text.Encoding.UTF8
        dim i as integer
        for i = 0 to 1000
            Console.Write(ChrW(i))
            if i mod 50 = 0 'break every 50 chars 
                Console.WriteLine()
            end if
        next
    Console.ReadKey()
    End Sub
end module

您选择的控制台字体也可能不支持该特定字符.单击 Windows 工具栏菜单(类似 C:. 的图标)并选择属性 -> 字体.尝试一些其他字体，看看它们是否能正确显示您的角色:

It's also possible that your choice of Console font does not support that particular character. Click on the Windows Tool-bar Menu (icon like C:.) and select Properties -> Font. Try some other fonts to see if they display your character properly:
