问题描述

大家好，
如何在终端屏幕上编写unicode?你能帮我吗?非常感谢.........
我正在使用串行端口类，并且我有serialPort.Write(ê").但这会在最终屏幕上显示一个字符Ω:D

推荐答案

这不是我们可以简单回答的问题:甚至不可能.

如果您的意思是说您有一个终端，例如通过串行端口(RS232或类似端口)连接到您的PC的VDT(诸如VT220之类的哑终端设备)，那么它将完全取决于终端本身可以显示，以及您如何告诉它执行此操作.我不知道没有使用Unicode的终端机(哎呀，我不知道他们还是在制作VDT！)-我那天他们都使用ASCII，这可能会为您的问题提供解决方案.
而不是将数据作为字符串发送到终端，而是将其作为字节数组发送，并使用ASCII编码而不是Unicode:

This isn''t a question we can answer simply: it may not even be possible.

If you mean that you have a terminal as in a VDT (a dumb terminal device such as a VT220, or similar) connected to your PC via a serial port (RS232 or similar) then it is going to depend on exactly what the terminal itself can display, and exactly how you tell it to do that. I know of no terminal that uses Unicode (heck, I didn''t know they still made VDTs!) - they all used ASCII in my day, which may present a solution to your problem.
Instead of sending your data to the terminal as a string, send it as a byte array instead, and use ASCII encoding instead of Unicode:

string s = "Hello!\r\n'être et avoir' is a French documentary, made in 2002";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(s);
mySerialPort.Write(bytes, 0, bytes.Length);

我不保证它将对您需要的所有字符都有效，但是它代表了更好的机会！

I don''t guarantee it will work for all characters you need, but it stands a better chance!
