Why a bad idea? I’m curious to know. From what I can see, unicode glyphs looks 
pretty good and comes for free, and as Yuri said they could even work on text 
terminals. At least for the simple shapes like ▶/▼, they seems to be a good 
option.

BTW, as for the location of the code that inserts those icons, I’ve found them 
in cus-edit.el. They are inserted by custom-visibility widget (using 
widget-image-insert).
