曾彪彪的个人博客 -- vs code encoding issue

## Issues
While executing a application with c++, it always display error code in console for Chinese character. The root cause is that the application's charset is different with the terminal. The default charset for appliction is utf-8, and my terminal charset is GBK as default.

There are two solution to solve this issue.

## Solution 1. (Not recommend)
Change the default file encording to GBK by following below steps.
- open File->Prefererences->Settings or press "Ctrl + ," to open setting UI.
- In the setting windows, select File->Text Editor->Files->Files:encoding, change the utf-8 to GBK.
- Rebuild your code, the Chinese character should be diplayed correctly.

## Solution 2.
Add args "-fexec-charset=GBK" in tasks.json. Before you build the source code, vs code will create a tast.json automatically. Open the task.json, and add args "-fexec-charset=GBK: as below.
```json
{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "build",
            "command": "C:\\msys64\\ucrt64\\bin\\g++.exe",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                "-fexec-charset=GBK"  // Add this arg to build the application as GBK encoding.
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}

```

By the way, if your system is english, the debug console also can't show Chinese correctly, and it seems this issue can't be addressed even though I do a lot of research. In this case, you should use external terminal in your launch.json as below.

```json
{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": true, // use external console instead of integrated terminal.
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\msys64\\ucrt64\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                },
                {
                    "description": "Set Disassembly Flavor to Intel",
                    "text": "-gdb-set disassembly-flavor intel",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "build"
        }

]
}

```
