Encoding West African Adinkra sysmbols

[Kyekyeku Opoku-Pong]

Hello,I hope this is the right forum to seek help.I am looking for the 
possibility of encoding Adinkra symbols used extensively in Ghana and West 
Africa. There is information on Adinkra symbols and their meanings at: 
http://www.adinkra.org/htmls/adinkra_index.htm
How do I go about the process of getting the symbols approved for Unicode.
Thank you,Kyekyeku
