I often use foreign alphabet letters (specifically Greek) for placeholders for certain characters when I'm building a story. I think it would be handy for CL to be able to display these characters.
Times Roman has the extended characters, it's just a pain to have to enter them from the character map. I'm not savvy enough to have figured out how to get them (or which one I'm getting) through simple keyboard commands. In Word, I was using the symbol font which accesses them through straightforward keystrokes.
