If ROTATE is coded as URWDWH, how is COUNTING coded in that language?

Let's analyze the relationship between the letters of the word ROTATE and its code URWDWH:
* R (+3) $\to$ U
* O (+3) $\to$ R
* T (+3) $\to$ W
* A (+3) $\to$ D
* T (+3) $\to$ W
* E (+3) $\to$ H

Each letter is shifted forward by $+3$ positions. Applying the same rule to COUNTING:

* C (+3) $\to$ F
* O (+3) $\to$ R
* U (+3) $\to$ X
* N (+3) $\to$ Q
* T (+3) $\to$ W
* I (+3) $\to$ L
* N (+3) $\to$ Q
* G (+3) $\to$ J

Hence, COUNTING is coded as FRXQWLQJ.
