Unity Android Logcat插件 输出日志中文乱码解决

• 背景

        之前安卓真机调试看日志，一直用的是Android Studio自带的adb命令进行看日志，不太方便，改用Unity自带的安卓日志插件时，存在中文日志乱码问题。

• 插件安装

        基于Unity6000.1.11版本：Window -> Package Management -> Package Manager,即可打开包管理工具，选择Unity Registry分类，找到Android Logcat插件，导入即可。

• 插件使用

        打开插件：Window -> Analysis -> Android Logcat，手机开启调试模式后，使用数据线连接电脑，在该插件面板默认会自动选择手机并输出日志(需手机先运行程序，每次运行后，每次选择)。可在顶部选择要调试程序的包名，输出的日志更整洁。

• 乱码解决

        找到插件源码：Editor/AndroidLogcatMessageProvider.cs

        public override void Start()
        {
            var arguments = LogcatArguments();
            AndroidLogcatInternalLog.Log("\n\nStarting logcat\n\n");
            AndroidLogcatInternalLog.Log("{0} {1}", m_ADB.GetADBPath(), arguments);
            m_LogcatProcess = new Process();
            m_LogcatProcess.StartInfo.FileName = m_ADB.GetADBPath();
            m_LogcatProcess.StartInfo.Arguments = arguments;
            m_LogcatProcess.StartInfo.RedirectStandardError = true;
            m_LogcatProcess.StartInfo.RedirectStandardOutput = true;
            m_LogcatProcess.StartInfo.UseShellExecute = false;
            m_LogcatProcess.StartInfo.CreateNoWindow = true;

            //中文乱码修复，增加两行代码
            m_LogcatProcess.StartInfo.StandardOutputEncoding = System.Text.Encoding.UTF8;
            m_LogcatProcess.StartInfo.StandardErrorEncoding = System.Text.Encoding.UTF8;

            m_LogcatProcess.OutputDataReceived += OutputDataReceived;
            m_LogcatProcess.ErrorDataReceived += OutputDataReceived;
            m_LogcatProcess.Start();

            m_LogcatProcess.BeginOutputReadLine();
            m_LogcatProcess.BeginErrorReadLine();
        }

        找到插件源码：Editor/AndroidTools/Shell.cscishi 

        internal static ShellReturnInfo RunProcess(ShellStartInfo startInfo)
        {
            Process process = new Process();
            process.StartInfo.FileName = startInfo.FileName;
            process.StartInfo.Arguments = startInfo.Arguments;
            process.StartInfo.WorkingDirectory = startInfo.WorkingDirectory;
            process.StartInfo.UseShellExecute = false;
            process.StartInfo.RedirectStandardOutput = true;
            process.StartInfo.RedirectStandardError = true;
            process.StartInfo.CreateNoWindow = true;

            //中文乱码修复，增加两行代码
            process.StartInfo.StandardOutputEncoding = Encoding.UTF8;
            process.StartInfo.StandardErrorEncoding = Encoding.UTF8;

            ...

        }

此时，日志就能够正常显示中了。
