Do non-keyboard characters make my password less susceptible to brute forcing?

Bruteforce tries cracking the hash with every possible combination of letters.

Then, If I'll use an special Unicode char, as ♥ or ¿, will it increase my security?

I'm talking about NTLM passwords.

Yes,

In the sense you are increasing the entropy of your password, making it harder to perform bruteforce attacks against.

I am from a country where we use non-english letters. This allowed me to use characters not common used in a charset by a brute-force applications, but I effectivly locked myself out of my webmail when I used a computer without my regional keyboard settings.

Edit:

Googling NTLM + unicode shows that there is support for unicode as NTLM password.
