no, I want to express, that this "right to left" is part of the functionality of the hd44780 compatible functions. It should work with the SPLC780D1 also. I just don't have a SPLC780D1 around currently, only a hd44780.
Can you please give it a try?
/*******************************************************************************
Support of Cyrillic characters on liquid crystal display
5036_Convert_Hebrew
This sketch includes several LCD hardware:
- Support LCDs with SPLC780D1 015A ROM (sold as "Hebrew" but also contains some Cyrillic) - https://s.click.aliexpress.com/e/_DBc5znh
You can switch through the examples by pressing enter in the serial monitor.

I'm not working with platformio, hence I don't know what's needed for that.
Further more, is there any chance you could provide me a picture of the LCD showing one row in Hebrew with my sketch for my homepage?
edit: code updated (Latin left to right, Hebrew right to left)
