I faced a similar issue when trying to print Arabic characters, and I tried several packages. However, I eventually found some useful Flutter SDKs for Thermal Printers that offer support for multiple languages:

bluetooth_thermal_printer - This is a Flutter plugin that allows you to use a Bluetooth thermal printer only for Android devices.
blue_print_pos - This is a Flutter plugin that enables you to use a POS (point of sale) system on both Android and iOS devices.
This is the updated forked blue_print_pos SDK which I used in JAN, 2023. You can use it without facing any issues.
