What is the diet of the binturong?

A Binturong's fur smells like popcorn! I experienced this for myself at the San Diego Zoo, when I interviewed the zoologist and "met" their Binturong.

Looks like a cross between a raccoon and a wolverine

This is the first time I have ever seen or read anything about this creature, they look a bit scary but seem really interesting and if they smell like popcorn they must be good guys! 👍
