I'm trying to read the csv file with Cotlin, but the letters are broken.

class GetTxtActivity : AppCompatActivity() {

    private val vBinding by lazy {ActivityGetTxtBinding.inflate(layoutInflater)}
    val getCsvCode:Int = 1

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(vBinding.root)

        vBinding.getCellBtn.setOnClickListener{
            val downUri = Uri.parse("")
            openCsvFile(downUri)
        }
    }

    private fun openCsvFile(pickerInitialUri: Uri){
        val intent = Intent(Intent.ACTION_OPEN_DOCUMENT).apply {
            addCategory(Intent.CATEGORY_OPENABLE)
            type = "text/csv/dnf/*"
            putExtra(DocumentsContract.EXTRA_INITIAL_URI, pickerInitialUri)
        }
        startActivityForResult(intent, getCsvCode)
    } //openCsvFile End

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, requestCode, data)
        if(requestCode == getCsvCode && resultCode == Activity.RESULT_OK){
            data?.data?.also { uri ->
                val inp = getContentResolver().openInputStream(uri)
                inp?.bufferedReader()?.useLines { lines->
                    for(item in lines){
                        Log.d("test", item)
                    }
                }

            }
        }
    } //onActivityResult End

} // GetTxt End
