This is an essential application on my Linux Mint 18
Interface is better than Win, but hard to find many unicode characters.
The search makes it easy to find the character you need when you cannot remember or figure out which group it is in. Lots of groups, but that is what makes it complete.
Helpful. But I almost never find what I need.
Great little app for what it does.
Not the simpliest character map to navigate, but it has a search feature that helps, and boy is it ever full of selections!
