They're called special characters.
I'd love it if we were able to put special characters in our tags. For example: ☆, ❤, ❦, ♞ ect.
With having a lot of characters, I'd like to be able to quickfind certain groups with maybe just a single icon to represent things I still need to do/keep track of. (For example: ≈ = Undeveloped/ needs to be worked on ❀ = Fully Developed)) This is a bit of a lazy suggestion since Sure it can just be written out. But it could be helpful in the way of the length of having multiple tags for things condensed into a few little icons instead of long words. Especially if a lot of tags are used. This would be especially great since we can inform what everything means in Profile or character blurbs. Just thought I'd throw it out there as it might make things convenient for others as well
