Hi, I use the U8G2 library on STM32, how do I write Persian/Arabic letters and numerals on the display? I used the below code to print the "سلام" string on display, but it printed on display like "س‌ل‌ا‌م". What is the problem and how should I fix it?

u8g2_FirstPage(&u8g2); do { u8g2_SetFont(&u8g2, u8g2_font_iranian_sans_12_t_all); u8g2_DrawUTF8(&u8g2, 40, 10, "سلام"); } while (u8g2_NextPage(&u8g2));

This is a difficult issue. It had been discussed multiple times, but as of now there is no proper solution in u8g2 itself. I suggest to look into the existing issues, maybe there is something useful.
