Make BluetoothClient send ANSI characters

Hello.
I am using the BluetoothClient component.
Tell me how to configure ai2 so that the phone application transmits characters via Bluetooth in Windows-1251 encoding.
For example, I have a number in .hex "0xA9" through BluetoothClient, the symbol "©" should be sent to the air.

Just changing CharacterEncoding UTF-8 to Windows-1251 doesn't give me the desired result
How to solve this or recode it so that the Bluetooth of the phone sends characters from "0xA9" to "0xFF"?
