从System.in获取Unicode值 [英] Getting unicode values from System.in

问题描述

我创建了一个Scanner，它从System.in获取输入，以便可以从控制台获取输入.

I have created a Scanner that gets input from System.in so that I can get input from the console.

Scanner scanner = new Scanner(System.in, "UTF-8");

当我这样做

String s = scanner.next();

，然后在控制台中输入Слово דבר，字符串的值将变为???? ???.

and then input Слово דבר in the console, the value of the string becomes ???? ???.

控制台能够显示Unicode字符，但是为什么我看不到它们?

The console is able to display Unicode characters, but why can't I read them?

推荐答案

假定System.in是UTF-8编码是不安全的.有关某些解决方法，请参见此问题.

It's not safe to assume System.in is UTF-8 encoded. See this question for some workarounds.
