adb shell input text error

[madroidmaq]

Using adb shell input text will result in the following error message when multiple strings are entered into the text box:

adb -s emulator-5554 shell input text "app agent test"

The error message is as follows:

Exception occurred while executing 'text':

    def text(self, input_str):
        input_str = input_str.replace(" ", "%s")
        input_str = input_str.replace("'", "")
        adb_command = f"adb -s {self.device} shell input text {input_str}"
        ret = execute_adb(adb_command)
        return ret

I noticed that the project has implemented simple adaptations by replacing spaces and single quotes, and it works fine in my tests. I'm not sure if this is due to the input method?
