Opening Unicode files

[majidkamali1370]

Hi.
I created a .txt file and wrote in it "Hello World" (without double quotation) and saved it with Unicode Encoding.(Little Endian)
When I open it in C++, the first two bytes are 0xFF and 0xFE. what are these?
Thanks :-)

It's the BOM:

Basically it identifies the file endianness. FF followed by FE indicates little endian, whereas FE followed by FF indicates big endian.
