if ($_GET['i'] == "par1") {
  func1();
} else if ($_GET['i'] == "par2") {
  echo "şşşıııİİİ";
  func2();  
} else if ($_GET['i'] == "par3") {  
  echo "şşşıııİİİ";
  func3();  
} 
this is my export2excel.php file and func1,2,3 are in functions.php file and produces table output all work well except character encoding in a strange way. I am using utf-8 encoding for all my files. 2nd else if statement above produces healthy encoded output but rest 2 are encodes my output with strange characters like "BÜTÇE İÇİ". it is "BÜTÇE İÇİ" in turkish.
in short. same files, same encoding, same database but different results.
any idea?
