Gets or sets the font for the selected text in Text.
Notes
Start is the starting position in Text (0-based). The default value for Length is 1. Returns a String. Use assignment syntax to set the value.
Note: On macOS, if Start + Length is greater than the Length of the String, then an OutOfBoundsException is raised. On other platforms, the change will apply to the end of the string.
Example
Change the font for some text in a TextArea:
TextArea1.StyledText.Value = "Hello, World!"
TextArea1.StyledText.FontName(7, 5) = "Courier"
TextArea1.StyledText.FontName(7, 5) = "Courier"
