I don't know if it's the result of updating Lion, or whether old age has played tricks with my memory, but things have changed!

I used to click an icon in the menu bar which brought up huge selections of characters that I could drop into the document I was writing at the time. There is still a character viewer, but it doesn't have much in it and not the neat fractions, half, fifth, three quarters etc. that I need from time to time. I have found some in System Preferences - Language & Text. But where has the full character list gone?

Writing to my grandchildren means using many signs, symbols and pictograms to make it interesting, but Nisus won't display some of the fonts correctly. For example, Wingdings, Zapf Dingbats and Apple Color Emoji are installed, but Nisus will not display them and shows them in red in the toolbar.

Please advise.
