cannot print in ios cyryllic text like "Привет, мир!"

[zhake555]

When printing text in Cyrillic, it prints incomprehensible characters. On android, I solved the problem by adding this line "esc.addSelectCodePage(EscCommand.CODEPAGE.PC866);" and adding next to the text the name of the encoding " esc.addText(content, "cp866");" in the PrintContent.java file. But so far I have not been able to solve the problem on ios. What and where to write can you tell?
