I met this website

Which basically explains that there exists a graphite fonts which when used with 
openoffice translate its translates to sign writing. 

May I ask you if I am correct on this please? I downloaded openoffice but 
unfortunately I have not yet managed to install the ISWA graphite font to make 
use of this font.

May I ask you whether you can help me with this please?

Thanks in advance for your time
