Locate the page you wish to add a special character to, and click the Edit tab.
Select the location in which to add the special character (move the cursor to that position). Or, in this case, highlight the character you wish to replace with a special character (here we are replacing an 'n' with an 'ñ').
Click the Insert button in the content editor menu then click the Ω Special character item.
In the popup window, find the character you wish to add and click it.
The special character will now be added.
When you are done with your edits and changes, publish the page.
