How to fix the problem of garbled characters in the Idea console?

To solve the problem of garbled characters in the console, you can try the following methods:

1. Set the console encoding: Input the command chcp 65001 in the console to set the encoding to UTF-8.
2. Change console font: Right-click on the title bar, select “Properties”, and choose a font that supports the Unicode character set from the “Font” tab, such as “Consolas” or “Lucida Console”.
3. Change the default encoding of the IDE or editor: In the IDE or editor, set the default encoding to UTF-8 to ensure that files are saved in UTF-8 encoding.
4. Check the encoding of the source code files: Make sure that the encoding of the source code files matches the console encoding, such as UTF-8.
5. Use Unicode escape sequences: If the garbled text is caused by the console being unable to display certain special characters correctly, you can use Unicode escape sequences to substitute these characters, such as \uXXXX.
6. Utilize third-party libraries or tools: If the above method is ineffective, you can try using third-party libraries or tools to handle the issue of garbled text in the console, such as using the chardet library to detect file encoding or using the iconv tool to convert file encoding.

It should be noted that the issue of garbled text may be caused by various reasons, and the solution may vary. Therefore, it is recommended to choose the appropriate solution based on the specific situation.
