Can't use special characters in profile feilds

In the forum one can't ad special characters to some of thefeilds in account settings

if i ad my google+ account to my profile ill get this error massages

The field “Google+” has invalid characters, only alphanumeric characters are allowed.

my google+ is account name is "Jesper Møller"

it looks like the system won't accept space and the letter ø

this goes for all the feilds:

YAHOO MESSENGER:

JABBER ADDRESS:

FACEBOOK:

TWITTER:

SKYPE:

the user guide says to use username

but for people like mee that have special letter like Ø in ther name we are not able to use those feilds ??

other feilds on the bord accepts danish letters like æ ø and å it s also the case for swedish and norwegian special letters
