SendText works wierdly on special characters

[graysuit]

Describe the bug

Is that expected we need to escape special characters ? or may be better library should do itself to be safer, right ?

Steps to reproduce the bug

Sub Main()
    Dim client = New AdbClient()
    client.Connect("emulator-5554")
    Dim device = client.GetDevices().FirstOrDefault()
    Console.WriteLine(device.Model)

    PassElement.ClearInput()
    PassElement.SendText("#")     'Result = AdvancedSharpAdbClient.Exceptions.InvalidTextException: Text contains invalid symbols
    PassElement.SendText("\#")    'Result = #
    PassElement.SendText("$")     'Result = $
    PassElement.SendText("a$a")   'Result = a
    PassElement.SendText("a\$a")  'Result = a$a
End Sub

Currently I use this as workaround:

Function Escape(Str As String) As String
    Dim RestrictedChars = "~@#$%^&*()_+=-!".ToCharArray()
    For Each R In RestrictedChars
        Str = Str.Replace(R.ToString(), $"\{ R.ToString()}")
    Next
    Return Str
End Function

PassElement.SendText(Escape("~!@#$%^&*()_+=-"))

Because it is send command to Android Shell. So these spaical characters should add \ to escape...

Per my analysis this is adb issue. Currently using ADbkeybaord as helper. It works.

Function SendText(client As AdbClient, device As DeviceData, Text As String)
    Return RunAdb(client, device, $"am broadcast -a ADB_INPUT_CHARS --eia chars '{ConvertToUnicode(Text)}'")
End Function

Function ConvertToUnicode(Input As String) As String
    Dim Output = String.Empty
    For Each c As Char In Input
        Output += AscW(c).ToString() + ","
    Next
    Return Output.TrimEnd(","c)
End Function

Function RunAdb(client As AdbClient, device As DeviceData, cmd As String) As String
    Dim receiver As New ConsoleOutputReceiver()
    client.ExecuteRemoteCommand(cmd, device, receiver)
    Dim Out = receiver.ToString()
    receiver.Flush()
    Return Out
End Function

Thank so much for great work!
