Remove duplicate characters on string

Hi there, is it possible to remove duplicate characters on string ?

Example of the desire output:

HELLO WORLD -> HELO WRD

DIRECTOR -> DIRECTO

9999 -> 9

??? -> ?

Regex

Fuzzy Match

Optimization

@binu_acs Why would you not just using the Unique Tool, where you've used the Tile and Filter Tool?
