Printooth character code don't work, need cyrillic

Displays characters when sending Cyrillic for printing. I checked all available encodings in the library by printing the text "Тест" and got no result.

The printer supports the Cyrillic alphabet, I checked it on the application from the market:

Here is the part of the code where I set the print data:

public void testPrint(View view){    
     ArrayList<Printable> printables = getTestPrint("Тест");
     PairedPrinter printer = new PairedPrinter(name, mac);
     Printooth.INSTANCE.printer(printer).print(printables);
}

 public static ArrayList<Printable> getTestPrint(String text){

    ArrayList<Printable> printables = new ArrayList<>();

    Byte lineSpacing = (byte) Settings.lineSpacing(context);
    int spaceAfter = Settings.spaceAfter(context);

    printables.add(gerRawPrintable());

    Map<String, Byte> bytes = Printer.getCharacterCode();

    for(var entry: bytes.entrySet()){
        printables.add(new TextPrintable.Builder()
                .setText(entry.getKey() + " - " + text)
                .setCharacterCode((byte) entry.getValue())
                .setCustomConverter(new DefaultConverter())
                .setAlignment(DefaultPrinter.Companion.getALIGNMENT_LEFT())
                .setNewLinesAfter(spaceAfter)
                .setLineSpacing(lineSpacing)
                .build()
        );
    }

    return printables;

}

 public static RawPrintable gerRawPrintable(){
      return new RawPrintable.Builder(new byte[]{27, 100, 4}).build();
 }

  public static Printable getPrintElement(String text, Byte lineSpacing, byte characterCode){

      return new TextPrintable.Builder()
         .setText(text)
         .setAlignment(DefaultPrinter.Companion.getALIGNMENT_LEFT())
         .setNewLinesAfter(Settings.spaceAfter(MainActivity.context))
         .setLineSpacing(lineSpacing)
         .setCharacterCode(characterCode)
         .build();
  }

 public static Map<String, Byte> getCharacterCode(){
    Map<String, Byte> bytes = new HashMap<>();

    bytes.put("ARABIC CP720", DefaultPrinter.Companion.getCHARCODE_ARABIC_CP720());
    ...
    bytes.put("WEU", DefaultPrinter.Companion.getCHARCODE_WEU());

    return bytes;

}

I solved the problem by sending the text to print using the RavPrint class:

    byte[] bytes = text.getBytes(StandardCharsets.UTF_8);
    printables.add(new RawPrintable.Builder(bytes).setNewLinesAfter(1).build());
