Dp
The dp symbol used to be used to be part of a lost internet language, until an archaeologist (who doesn't want to be credited), discovered the the following symbol:
Everyone and their mom wanted to learn how to type this mysterious symbol, but it is said only those who have mastered the art of the binary language can make it. As for its meaning, it is believed to mean the following:
Uli gslhv dsl hloevw gsrh xrksvi
Gzop gl gsv zmxrvmg erkvi
Zmw urmw gsv wrznlmwh lu gsv zmxrvmg grnvh
Gibrmt gl gsrmp lu hlnvgsrmt gszg isbnvh
Said archaeologist believes this is a cipher. I encourage you to try and crack it.
Good luck ;)
