Localization don't work with the russian text, only english

[AmazingDeveloper2]

I make a localization for my game on Unity3d. I have a text file with russian text and file with the same english text. When I try to display rusian text, I can’t see it in the game, but english text I can see (if replace russian text to english on the same string). Why is it happens?

//===== script 'LoadTextFromFile ' ======

    public TextAsset textFileButtonsEng;
    public TextAsset textFileButtonsRus;

    private string[] dialogLinesButtonsEng;
    private string[] dialogLinesButtonsRus;

    private int curentLanguageIndex = 1;

   void Start()
    {
        // if file exists
        if (textFileButtonsEng && textFileButtonsRus)
        {
            dialogLinesButtonsEng = (textFileButtonsEng.text.Split("

“[0]));
dialogLinesButtonsRus = (textFileButtonsRus.text.Split(”
"[0]));
}
}

    public string GetLineOfText(string fileName, int lineNumber)
    {
        switch (fileName)
        {
            case "tasks":
                if (curentLanguageIndex == 0)
                    return dialogLinesTasksEng[lineNumber];
                else if (curentLanguageIndex == 1)
                    return dialogLinesTasksRus[lineNumber]; break;
        }


//========== other script ==========

public Text textTipsTasksComponent;
public LoadTextFromFile loadTextFromFile;
textTipsTasksComponent.text = loadTextFromFile.GetLineOfText("tasks", 25);

It is Arial font and I can see russian text when type it by myself like on the screenshot below.

You can do this:
1- open txt in Visual Studio.
2 - do File->Advanced Save Options.
3 - Encoding → UTF8.
4 - Line Ending → CR LF.
5 - Save file.
