OpenDNS - password special character - attention - pfSense 2.3

[mammifero]

Good morning to all
i write from Italy, excuse me for my bad English

i have created a new account on OpenDNS and with the same credential i was able to login to DNS-O-Matic service

when i try to configure Dynamic DNS under pfSense with my username and password previously created
i always obtain the error
"The DNS-O-Matic username or password specified are incorrect"

OpenDNS ask you to use special character for the password
Password must contain at least one digit and one special character (for example: *, $, or π)
i have put in my password the following character:

£

BAD BAD but very BAD IDEA

only after 2 hours i decide to change the £ with a *
SUCCESS
/services_dyndns_edit.php: DNS-O-Matic (pfsense): (Success) IP Address Changed Successfully!

Regards
