Invalid character in the given encoding. Line 2, position 1 error.

[Zyr0s]

I have zero understanding of this error. I have never encountered this error before and don't get why i am having it, this started occurring just after i crashed (not blue-screened, cable in the back of my computer got knocked) my characters are legitimate, i have never been banned nor have any of my characters been involved in statpadding or any other activities that would get me banned/wiped from the census. I do not know which character this is, i have a suspicion it is my BR 100 (Zyr0s, which has incredibly bad stats and should be the most average character on the list i put in). My OS is Windows 7 Ultimate Edition.

Has anyone else had this issue in the past as I haven't been able to find a thread or post linked to this.
