Design applications such as Adobe InDesign and Illustrator offer an option to view the glyphs pallet, and manually select the symbols you need. Text editors, such as Apple Pages, don’t come with such options, and in this case you would need to type the character you need directly. Go to a specific font presentation page to view the glyphs the fonts contain, and when you find the character you need, you can copy and paste it, if it has a Unicode code point.
