I recently discovered the compose key. It's wonderful to type Compose-> and get a Unicode right-arrow (→).

I know I can add my own, but where can I find a complete chart of the defaults?

The largest list I could find is this one at freedesktop.org. However, it seems imperfect too: For example, it lists a combination ComposeFU as producing "reversed hand with middle finger extended", which—quite disappointingly—doesn't work for me…

Is there somewhere these are stored on my actual live system?
