ADBKeyBoard may help to solve the unicode input related issues

[rapiz1]

I have read some issues related to non-ASCII characters input like supporting non-English keyboard layout, Chinese input and so on.

One of the ideas that tried to solve the problem was to use the computer's input method, and due to something like adb input text '世界你好' not working, failed.

So, if we can directly send unicode string to the device, we can solve the problem, right?
I did some searching on the Internet and have found this: ADBKeyBoard
Here's the steps I think will work ( Sorry for my limited knowledge on Java and Andord programming):

1. Invoke the computer's input method and get the character the user want to input.
2. Use ADBKeyBoard to send it to the phone.

But there is also one drawback: This may destroy the gaming experience because the phone no longer receives the key event.

But this can be work around:
We can enable ADBKeyBoard when the Android input method is detected, or just provide an option to enable ADBKeyBoard.
