乱码文件名导致应用崩溃

[CandyTek]

用户手机根目录里存放有乱码文件名的文件，使用dialog filepicker浏览至根目录，应用崩溃，编译demo，或者是项目里依赖filepicker都会崩溃。Android 9 控制台报错如下： 13:47:05.323 11046-11046 ang.demo.picke com...ng.demo.picker A java_vm_ext.cc:542] JNI DETECTED ERROR IN APPLICATION: input is not valid Modified UTF-8: illegal continuation byte 0xfa 13:47:05.323 11046-11046 ang.demo.picke com...ng.demo.picker A java_vm_ext.cc:542] string: 'ѧ?????˳ɼ???

找出问题了，是我调试的那台手机里根目录有个乱码pdf文件导致的。我使用了很多文件管理开源储存库，全部都会崩溃。在手机上，只有少数的文件管理app应用不会崩溃。可能这些app是用了某些另类方法来获取文件信息的。
