Using added text characters

Hi,

These holidays I decided to translate again FF6 for my kids, I did already some years ago, but lost it, and wanted to play it with them.

Back then I used FF3usME, so I decided to go again with it, find it an outstanding editor, Instead of replacing characters like @ or so, I decided to go adding new ones on the "empty" addresses, but now I don't know how to "call" them from the dialog editor...

Any idea how to do that? 

If you've got any other suggestion I'm open to them, I've got to explore several years of development in editing! My plan is to use FF3usME for everything I can, and complete with FF6Editor afterwards

Happy new year!
