How can I send println output to vscode terminal not debug console?

[n0111000]

Character corruption occurs for Japanese text while launching debug.
I heard I can avoid this by sending ouput to vscode terminal not debug console at following page.
microsoft/vscode#3550
How can I switch to terminal?
I cannot find such option in launch.json sample.
For example in Python launch.json, I can find "console" option.

"configurations": [
    {
        "name": "Python: Current File (Integrated Terminal)",
        "type": "python",
        "request": "launch",
        "program": "${file}",
        "console": "integratedTerminal"
    },

Please help to popularize kotlin and vscode in non-English world!

Sending the output to the integrated terminal is not yet possible.

I could imagine this being implemented by running the gradle command directly through the terminal and then attaching the debug server.

Still, I am unsure whether the encoding is an issue with the debug console or the debug server. UTF-8 support should be available throughout VSCode.
