So, when I do dub fancast/roles, I like to put little flags in the corner of the poster or role image to designate the dub and set them apart, but I was getting sick and tired of copy-pasting everything, so I made a quick database of flags for the most common dub languages for my convenience. If you want to use them for yours too, go right ahead, no credit needed! This includes most of the most common dub languages, plus a bonus blank one for any languages that might be missing.
