strings are drawn using Graphics in this library. (GDI +) emoji are drawn using TextRenderer. (GDI)

Sample Code

var text = "😀";

var location = new Point(100, 75);
var family = FontFamily.GenericSansSerif;
var fontSize = 60;
var fontStyle = FontStyle.Regular;
using (var font = new Font(family, fontSize, fontStyle, GraphicsUnit.Pixel))
{
    // Graphics -> GDI+
    g.DrawString(text, font, new SolidBrush(Color.Red), location);
}

Result

Sample Code

var text = "😀";

var location = new Point(100, 75);
var family = FontFamily.GenericSansSerif;
var fontSize = 60;
var fontStyle = FontStyle.Regular;
using (var font = new Font(family, fontSize, fontStyle, GraphicsUnit.Pixel))
{
    // TextRenderer -> GDI
    TextRenderer.DrawText(g, text, font, location, Color.Red);
}

Result

TextRenderer is included in System.Windows.Forms, so it may not be desirable to refer to it. (Can't support various runtimes ?? :worried:)
