Google apps script for Spreadsheet - russian symbol substitute as a question mark

Question

If you open a link in brazuere __ - that everything is OK, an entry is added in Russian. If the same link run from php script - it added a question mark. Here's the code dlyastranitsy pgoogl appps

 function doGet(e) {
  var ss = SpreadsheetApp.openById("14EWkOKE4QONFQ7UAi5Kf1vYnTgSXzCH_ZJZ5fzo3dIU");
  var ss = ss.getSheetByName('Лист');
  var rr=getFirstEmptyRowWholeRow(ss);
  ss.insertRowAfter(rr);
  Logger.log(e.parameter.tovar);
  ss.getRange('A'+rr).setValue(e.parameter.tovar);   
}
function getFirstEmptyRowWholeRow(ss) {
  var values = ss.getDataRange().getValues();
  var row = 0;
  for (var row=0; row<values.length; row++) {
    if (!values[row].join("")) break;
  }
  return (row+1);
}

Here is the code php file

function obrab_url($s){
    return str_replace(' ','%20',nl2br($s));
}
