The unicode entry tool in OS X 10.11 (the one displayed in your menu bar if you tick the appropriate box in the first tab of the keyboard settings) allows me to copy information about a symbol. There is an entry to this effect in the context menu of the symbol. However, I can't find an option to just display that information, so I always have to copy the text to some other application if I want to just read it. Am I missing something?
If you don't see Unicode data in right-hand sidebar, under your chosen glyph's Name, then you need to add Unicode to your list of categories on the left sidebar.
At the top left, click the Gear icon [it always looks greyed-out until you click it]
Select Customise List…
Scroll down the Select Categories list, open Code Tables & check Unicode.
[I've composited this picture, you won't really see both menus at once]
- Click Done & click any other glyph to make your new information display.
