Sometimes you need to add a special character like: © or € or an accented letter such as: é or è or å. This is easily done using the Add Special Character feature of the visual editor.
Place your editing cursor where you want the special character to appear. Click on the Add Special Character icon (framed in red above) and select the character you want and click on it. Voilà! Your special character is now added to your text and can be formatted just like any other text.
