Polskie czcionki w formularzu mailowym Opcje

[Kzajko]

Nie mając dużego doświadczenia z php sciągnąłem z internetu gotowy skrypt umożliwiający wysyłania wiadomości po wypełnieniu formularza na stronie internetowej. Wszystko działa ok za wyjątkiem polskich czcionek. Emaile przychodza z z dziwnymi znakami, które pojawiają sie tam zamiast polskich czcionek.

Domyslam się ze trzeba wpisac linijke lub dwie kodu, który sprawi że polskie czcionki pojawią się. Jak to można zrobic?
