What happened to my Character viewer?

I upgraded to OS X El Capitan the other day. Ever since, I haven't been able to get the Character Viewer (they renamed it Emoji & Symbols) to show. At first it just wouldn't show if I was in Word; I was still able to get it to show when I was in TextEdit, so I was copying and pasting between TextEdit and Word (what a pain!). Now it won't appear anywhere! I use ʿ and ʾ all the time, plus I need the paragraph marker (not the pilcrow [¶], but this one §). I'm using the HTML entity on that last one because I can't find it on the keyboard. The ʿ and ʾ I have in my Syriac keyboard cheatsheet, so I'm just copying and pasting. But I can't use the HTML entity in a Word doc!

Frustrating! What is the keyboard command for the § sign? Or better yet, Apple! Fix the Character Viewer!

Update: the § is Option 5. But I still need the Character Viewer for some other characters!
