unicode字符在IntelliJ IDEA控制台中显示为问号 [英] unicode characters appear as question marks in IntelliJ IDEA console

问题描述

我试图使用System.out编写unicode字符（♠），并打印一个问号。

I'm trying to write unicode characters (♠) using System.out, and a question mark gets printed instead.

如何显示正确的unicode字符而不是问号？

How can I have proper unicode characters displayed instead of question marks?

我正在使用IntelliJ IDEA

I'm using IntelliJ IDEA on Windows, and trying to print from within the IDE.

推荐答案

文件编码是否正确配置？请参阅设置|文件编码使用UTF-8。打印♠对我有用，当我有IDE编码和所有文件设置为UTF-8。更改编码后可能需要重新编译。

Is the file encoding configured correctly? See that "Settings | File Encodings" uses UTF-8. Printing ♠ works for me when I have IDE encoding and all files set to UTF-8. Recompiling may be needed after changing the encoding.
