Input stream korean language error

I am having an issue with the java Scanner fuction. With the project, I am trying to input korean language to debug terminal and get the result. but when I put in korean language to the Scanner, the code doesn't recognize the input and save it as ? or blank space. It seems like the debugger is not accepting korean language.

Environment

• Operating System: window 11
• JDK version: jdk 17
• Visual Studio Code version: 1.88
• Java extension version: v0.25.15
• Java Debugger extension version: v0.57.0

No source files, tests, or entry points are named. Start by reproducing the Scanner input case with Korean text under the listed Windows 11, JDK 17, VS Code, and Java debugger versions; done means Korean input remains intact in the debug terminal and search output.
