The default Safari bookmark bar has a link to “Apple”, and another “Apple” labeled RSS feed of Mac news. You can save space by replacing the word “Apple” with the apple symbol: . (Anybody reading this on a non-Mac will likely see a question mark or an empty square instead of the symbol which is the apple with a bite out of it logo.) This symbol can be found in the Special Characters window as Unicode F8FF (decimal 63743), or generated by shift-option-K.
Other Mac specific symbols can be found at MacBiblioBlog.
