Android's adb shell input text command does not support characters outside of the ASCII range.

This means that you cannot prompt the LLM to:

Click on Search, type 日本 and submit

A solution for this is to use the clipboard. mobile-mcp can detect if com.mobilenext.devicekit is available on the device, and if so, it will:

1. Copy the text to type into Android's clipboard
2. Submit a KEYCODE_PASTE, to paste clipboard onto the focused input field
3. Clear the clipboard on the Android device

Simply install com.mobilenext.devicekit apk on your device. You can copy-paste these commands to download and install:

curl -s -O -J -L https://github.com/mobile-next/devicekit-android/releases/download/0.0.10/mobilenext-devicekit.apk
adb install -r mobilenext-devicekit.apk

From this point onwards, mobile-mcp will attempt to use devicekit every time you try to input a text that is not fully ascii.
