Im sending a message through a contact form in the usual manner

PHP Code:
mail("$to","$title""$message","From: webmaster@suchandsuch.com""-froot@suchandsuch.com"); 
But I get a problem as one of the forms on the site is in Russian and as such users are typing Russian text into the form. When the message arrives all the Russian text has been converted into gibberish.
