I tried the following code:

  Print "TextBox font: "; TextBox1.Font.ToString()
  TextBox1.Text = UnBase64("8J+OhPCfjrg=")
  Print "Label font: "; Label1.Font.ToString()
  Label1.Text = UnBase64("8J+OhPCfjrg=")

on my Manjaro.

Apparently these unicode emoji are supported by GTK+, (i.e. Pango) 
whatver the font.

But for Qt5/Qt6, it displays something when using very specific fonts, 
and in the case the TextBox works badly. Otherwise it displays boxes 
(meaning "unknown glyph").

So I would say that emoji are not really supported by Qt at the moment?
