js mobile printing by APD

Im use ZEBRA iMZ320 mobile printer and MC3110 (WM). Use Bluetooth
connection. My js code is:
function print(str) {
var printerID = 'BZ:1|0022583CBD61';
apd.PSExternal(261, printerID);
apd.PSExternal(270, "");
str =
'^XA^MMT^PW559^LL050^LS0^FT27,40^A@N,15,15,TT0003M_^FH^CI28^FH^FDÀÁÂÃÄŨÆÇÈÊËÌÍÎÏÐÑÒÓÔÕÒÖ×ØÙÜÚÝÞßàáâãäå¸æçèêëìíîïðñòóôõòö÷øùüúýþÿ^FS^CI0^PQ1,0,1,Y^XZ'
apd.PSExternalEx(266, str);
apd.PSExternal(271, "");
}
Right printing only part of string - 'ÐÑÒÓÔÕÒÖ×ØÙÜÚÝÞßàáâãäå¸æçèêëìíîï'.
Parts 'ÀÁÂÃÄŨÆÇÈÊËÌÍÎÏ' and 'ðñòóôõòö÷øùüúýþÿ' not printing or printing
ubnormaly. But from Zebra setup Utility this zpl command printing all
right. Also it printing right by using rhomobile bluetooth device
capability technology
(send_string('^XA^MMT^PW559^LL050^LS0^FT27,40^A@N,15,15,TT0003M_^FH^CI28^FH^FDÀÁÂÃÄŨÆÇÈÊËÌÍÎÏÐÑÒÓÔÕÒÖ×ØÙÜÚÝÞßàáâãäå¸æçèêëìíîïðñòóôõòö÷øùüúýþÿ^FS^CI0^PQ1,0,1,Y^XZ')).
