Visual Studio Code distorts ANSI characters-CodePudding

I have problems with Swedish national characters when using Rust in Visual Studio Code in Windows 11. It can be shown with the following program:

fn main() {
let abc = " ååå
ööö
äää";
println!("<---{}--->", abc);
}

When the program is run from the command line using "cargo run", the output is as follows:

<--- ååå
     ööö
     äää--->

Strangely, spaces are added at the beginning of lines 2 and 3. However, when the program is run in Visual Studio Code, the Swedish characters get distorted.

<--- ├Ñ├Ñ├Ñ
     ├╢├╢├╢
     ├ñ├ñ├ñ--->

How can I solve it? I work with text processing and this is a major problem.

EDIT: Since the problem doesn't appear on many systems, I add the technical data: Windows 11 Pro Version 10.0.22621 Build 22621; Visual Studio Code Version: 1.73.1 (user setup) Date: 2022-11-09 Chromium: 102.0.5005.167 Node.js: 16.14.2 Sandboxed: No.

The VSC terminal seems to use cmd since all cmd commands work.

EDIT 2: The problem is solved by adding the following:

    "terminal.integrated.profiles.windows": {
        "PowerShell": {
            "source": "PowerShell",
            "icon": "terminal-powershell",
            "args": [
                "-NoExit",
                "/c",
                "chcp.com 65001"
            ]
        },
    },

as the first parameter in settings.json and saving the changes.

- This answer is Windows specific. -

INFO: This answer describes you how can change your VSCode settings to force UTF-8 in your console. An alternative to this answer would be to force UTF-8 system-wide, as described here: Using UTF-8 Encoding (CHCP 65001) in Command Prompt / Windows Powershell (Windows 10)

It seems that sometimes the windows shell doesn't use the correct UTF-8 code page.

You can tell VSCode to force a codepage in its shell using the following settings.

Open the Settings page (Shortkey: Ctrl ,)
Click on the button on the top right whose mouse-over text reads "Open Settings (JSON)"
Add the following lines:

   "terminal.integrated.profiles.windows": {
        "PowerShell": {
            "source": "PowerShell",
            "icon": "terminal-powershell",
            "args": [
                "-NoExit",
                "/c",
                "chcp.com 65001"
            ]
        },
        "Command Prompt": {
            "path": [
                "${env:windir}\\Sysnative\\cmd.exe",
                "${env:windir}\\System32\\cmd.exe"
            ],
            "args": [
                "/K",
                "chcp 65001"
            ],
            "icon": "terminal-cmd"
        },
    },

This will force the UTF-8 code page.

If it worked, opening a new shell should display Active code page: 65001.

Previous, deprecated settings:

If your shell is "CMD":

"terminal.integrated.shellArgs.windows": ["/K", "chcp 65001"],

If your shell is "Powershell":

"terminal.integrated.shellArgs.windows": ["-NoExit", "/c", "chcp.com 65001"],
