[Vscode Pulgin / Slint auto format] Chinese characters can cause long line formatting errors

[mcitem]

Bug Description

When a line is too long and contains Chinese characters, the extension formats incorrectly.

export component ExportedComponent {
    property <[{}]> items:[
        { icon: @image-url("1111111111111111111111111111111111111.svg"), text: @tr("账本"), modify: 0px },
    ];
}

export component ExportedComponent {
    property <[{}]> items:[
        { icon: @image-url("1111111111111111111111111111111111111.svg"), text: "账本", modify: 0px },
    ];
}

I don't quite understand why using the VSCode extension's auto-format on save results in errors. The screenshot is the result of automatic formatting after pressing Ctrl+S, while using the slint-lsp format command allows for normal formatting.

The problem is that slint-lsp interpret column as utf-8 byte instead of utf-16 byte
