delphi - Indy, IdTCPSever sending data in utf=8 charset -

i have problem conversion strings utf-8. use standard indy method sending conversion inside:

 acontext.connection.iohandler.writeln(utf8encode('ĄĘÓ')); 

but client reads them '???' - 3f 3f 3f in hex (i checked using wireshark too).

i use delphi xe , indy 10.

big help.

i found solution problem, think siplest using code below:

acontext.connection.iohandler.defstringencoding := tidtextencoding.utf8;
