java - Android byte to string charset -

i have problem charset convertion:

i have got messages udp server , data this:

byte[] adress= new byte [42]; 

after try displayed textview :

string str_adress= new string(adress,"utf-8"); 

instead of "ő" got "?"

how can solve that?

the utf-8 bytes ő c5 91.

as

log.v(tag, new string(new byte[] { (byte) 0xc5, (byte) 0x91 }, "utf-8")); 

outputs

ő 

i think looked in wrong place problem. it's coming somewhere else, reading udp message maybe.
