PopChar X 8.1
PopChar makes "typing" of unusual characters easy without having to remember keyboard combinations.
Whenever you need a special character, just lick the "P" in the menu bar to display a table of characters. Select the desired character and it instantly appears in your document. PopChar lets you search for characters by their names, find fonts that contain certain characters, get font info, view font previews, print font sheets, and much more.
