# Create new characters?

GROUPS:
 Greetings! As a part of my research, I am trying to define some new operators in wolfram mathematica. So far I've been able to use the existing special characters to this end. For example, the definition: a_ \[LeftArrow] b_ := "great sucess" Is working just fine, and can be cleared via Clear[LeftArrow] However, I want to define more operators with symbols that are not part of the special characters list. e.g. \[AwesomeSpecialCharacter]=Overscript["\[LeftArrow]","+"] (this obviously doesn't work) Is there a way to create such a new special character so I could later define it as an operator?
