output got messy code

[OhYee]

If I use python to run a file to show chinese in the task, it will output messy code in output.
And if I use javac to compile file in the task, it will output messy code in output.

I have read #50451 #38915 #35235, but it is no use.

It just occur when I use the third part program to output the chinese but not Windows command. And the terminal can run them without messy code.

The Python version is Python 3.6.0

May be the system language should be chinese

If my english is hard to understand, maybe use chinese is better.

使用Windows自带的指令输出中文内容没有乱码，但是task调用别的第三方应用再输出中文会乱码
这个问题只在output存在，在终端中正常

• VSCode Version: 1.24.0
• OS Version: Windows Insider Preview 17686.re_prerelease.180603-1447

Steps to Reproduce:

1. tasks.json

{
    "version": "0.1.0",

            "command": "echo",
            "args": [
                "中文"
            ]
        },
        {
            "taskName": "test2",
            "command": "cat",
            "args": [
                "${file}"
            ]
        },
        {
            "taskName": "test3",
            "command": "python",
            "args": [
                "${file}"
            ]
        }
    ]
}

You should upgrade to Tasks 2.0.0 which executes in the terminal which has full support to ANSI control characters and better encoding. See https://code.visualstudio.com/docs/editor/tasks#_convert-from-010-to-200 and https://code.visualstudio.com/docs/editor/tasks#_changing-the-encoding-for-a-task-output
