Used a Special Character in my Password

[Amatsukaze]

Like the title said, my old password had a special character in it and it had been working fine until today.

So today I decide to change my password, but due to the special character it wont let me.

So yeah... my old password needs to be typed correctly to change my password, but it won't let me due to a special character?

I also logged into my account from the website using my password with the special character so how does that even work?

Any idea what's going on? I am so lost...
Would I have to contact customer support for this? ;;

For example...

Lets say my current password were C00lKid#COOL (it's not)
To reset my password I'd have to type that as my current password, but from the error message I get it looks like that "#" does not let me change my current password.

But because it's in my current password I can't replace it with anything else or then my password becomes incorrect...
