Customize the Preview
In the preview area, you can change the size and color of the font, as well as the sample text that is displayed.
To enter a new text sample to be displayed, type in the text field. To enable underline or strike-through text attributes, click on the triangle to the left of the text field.
You can also enter Unicode characters if you know a character's Unicode code. For this, type "<decimal-code>;", "U<hexadecimal-code>;" or "U+<decimal-code>;"(without the quote signs and with <code> as the code)
