Support emoji text in charts

Emojis are a concise and fun way to express things in text.

Please add support for creating color emojis in text plots.

Windows has full emoji support: https://emojipedia.org/microsoft/
You can press Win + period buttons to insert an emoji in any text box.

When I try to draw text with emoji in a MultiCharts indicator, I only get "??" on the plot.

protected override void CalcBar()
{
    if (Bars.TimeValue.Minute % 10 == 0)
    {
        var point = new ChartPoint(Bars.CurrentBar, Bars.CloseValue);
        var textObj = DrwText.Create(point, "[put emoji here]");
        textObj.VStyle = ETextStyleV.Above;
        textObj.FontName = "Segoe UI Emoji";
    }
}

I tried "Segoe UI Emoji" and "Segoe Color Emoji" fonts.

Also it would be great if MultiCharts can support color emojis in PowerLanguage Editor Output.

Output.WriteLine("[put emoji here]"); // shows in black and white
