I made a text output program CEDITVIEW,
On the screen shows the hello world
MyEditCtrl. SetSel (0, 1);
MyEditCtrl. ReplaceSel (_T (" Hello, World \ r \ n "));
After using itself with the preservation of the TXT file, with a HEX editor opens as
00000000 h: 48 00 65 00 00 6 c... ; H.E.L.L...

Why didn't the beginning of the FF FE, how to modify the program, let it keep, automatically at the beginning of the file with FF FE, because want to use excel to open this text, if there is no FF FE will quote "damaged", I need to use notepad to open, then to save, to use excel to open,

See the code above, still can't understand how to deal with, I'm a beginner, can give a complete code, thank you very much!

M_TextArray refers to the text displayed in the view?
