Java CMD命令行输出中文乱码问题

1、使用aapt命令显示apk信息，发现中文的应用名显示为一串乱码

C:\Users\Administrator>aapt d badging C:\Users\Administrator\Desktop\zhztttb4_739_1_3250_3384_64662_ad.apk
package: name='com.zwzt.sszt4' versionCode='1596518241' versionName='1.0.8.1' platformBuildVersionName='6.0-2438415' compileSdkVersion='23' compileSdkVersionCodename='6.0-2438415'
install-location:'auto'
sdkVersion:'17'
targetSdkVersion:'22'

uses-permission: name='android.permission.ACCESS_FINE_LOCATION'
uses-permission: name='android.permission.ACCESS_COARSE_LOCATION'
uses-permission: name='android.permission.WRITE_SETTINGS'
uses-permission: name='android.permission.BLUETOOTH'
uses-permission: name='android.permission.BLUETOOTH_ADMIN'
uses-permission: name='android.permission.ACCESS_FINE_LOCATION'
uses-permission: name='android.permission.ACCESS_COARSE_LOCATION'
uses-permission: name='android.permission.INTERNET'
uses-permission: name='android.permission.READ_PHONE_STATE'
uses-permission: name='android.permission.ACCESS_NETWORK_STATE'
uses-permission: name='android.permission.CHANGE_WIFI_STATE'
application-label:'??????????€?'
application-label-af:'??????????€?'
application-label-am:'??????????€?'
application-label-ar:'??????????€?'
application-label-az:'??????????€?'
application-label-be:'??????????€?'
application-label-bg:'??????????€?'
application-label-bn:'??????????€?'
application-label-bs:'??????????€?'
application-label-vi:'??????????€?'
application-label-zh-CN:'??????????€?'
application-label-zh-HK:'??????????€?'
application-label-zh-TW:'??????????€?'
application-label-zu:'??????????€?'

2、出现乱码原因在于，cmd命令行默认编码是GBK,而aapt默认编码是UTF-8,鼠标放在命令行顶部，右键 - 属性

3、咱们可以在命令行输入CHCP 65001，回车，将当前窗口改为UTF-8编码，咱们再重新运行一下上述命令，发现aapt输出到cmd的中文正常显示出来了

Active code page: 65001

C:\Users\Administrator>aapt d badging C:\Users\Administrator\Desktop\zhztttb4_739_1_3250_3384_64662_ad.apk
package: name='com.zwzt.sszt4' versionCode='1596518241' versionName='1.0.8.1' platformBuildVersionName='6.0-2438415' compileSdkVersion='23' compileSdkVersionCodename='6.0-2438415'
install-location:'auto'
sdkVersion:'17'
targetSdkVersion:'22'
uses-permission: name='android.permission.INTERNET'
uses-permission: name='android.permission.VIBRATE'
uses-permission: name='android.permission.GET_TASKS'
uses-permission: name='android.permission.SYSTEM_ALERT_WINDOW'
uses-permission: name='getui.permission.GetuiService.com.ztyh.mg'
uses-permission: name='com.coloros.mcs.permission.RECIEVE_MCS_MESSAGE'
uses-permission: name='android.permission.DOWNLOAD_WITHOUT_NOTIFICATION'
uses-permission: name='android.permission.REQUEST_INSTALL_PACKAGES'
uses-permission: name='getui.permission.GetuiService.com.zwzt.sszt4'
uses-permission: name='android.permission.READ_EXTERNAL_STORAGE'
application-label:'纵横征途'
application-label-af:'纵横征途'
application-label-ur:'纵横征途'
application-label-uz:'纵横征途'
application-label-vi:'纵横征途'
application-label-zh-CN:'纵横征途'
application-label-zh-HK:'纵横征途'
application-label-zh-TW:'纵横征途'
application-label-zu:'纵横征途'

4、上述方法仅仅是可以解决cmd中文乱码问题而已，要是java -jar执行输出的是UTF-8编码的中文，按照上述方案修改，不仅仅依然还是乱码，而且缩成一坨了，有些没显示出来

C:\Users\Administrator>java -jar C:\Users\Administrator\Desktop\apkparser\game.jar

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>  apkϢ <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

uses-permission: name='android.permission.GET_TASKS'
uses-permission: name='com.android.launcher.permission.INSTALL_SHORTCUT'
uses-permission: name='android.permission.SYSTEM_OVERLAY_WINDOW'

5、对于java -jar执行输出的中文乱码问题，需要增加一个系统选项设置-Dfile.encoding=UTF-8即可

C:\Users\Administrator>java -Dfile.encoding=UTF-8 -jar C:\Users\Administrator\Desktop\apkparser\game.jar


>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>  apk基本信息 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>   apk权限信息  <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
uses-permission: name='com.asus.msa.SupplementaryDID.ACCESS'
uses-permission: name='android.permission.INTERNET'
uses-permission: name='android.permission.ACCESS_NETWORK_STATE'

uses-permission: name='android.permission.VIBRATE'
uses-permission: name='android.permission.GET_TASKS'
uses-permission: name='com.android.launcher.permission.INSTALL_SHORTCUT'

【备注】
假如是在Window PowerShell中执行 java -Dfile.encoding=GBK，会提示错误：错误: 找不到或无法加载主类 .encoding=GBK，需要换回原始的命令行工具cmd
