So, I'm a member on this Swedish video game forum, and now I'm trying to log in.
The problem is, I use the Swedish letter "ö" in my password, and the computer obviously doesn't grant this anymore: it used to do, but now it says "not a valid string of letters" an crap.

I've pretended to have forgotten my password as well, hoping that they would send me another one, but they just sent me my old password.
Wha the hell is this?
