Narrative:

The first officer's forward windshield began arcing. Shortly thereafter it cracked in several places. We followed ECAM; QRH and fom procedures; descended to FL230 and ultimately landed in ZZZ2. All parties were informed. We saw it and heard it. Requested a deviation from ATC. Declared an emergency. Left the track. Conferred with dispatch. Apparently the windshield controller caused the arcing and subsequently the cracking of the windshield.
