 <p>if you have an Apple, there is a very easy way to access all of the characters available to the "Character Viewer". In Sys Prefs -> keyboard -> input sources, select show input menu in menu bar. Bring up the character viewer and then make favorites of the N characters you need to access. Then, hit the small box to the right of char viewers search bar. The char viewer disappears, and what's left is a small window with your chosen char set. Position your cursor in your editor, click on the desired char in the favs.</p>
