And just a note that C compilers treat literal numbers as big endian.

So if you do this
wchar_t BOM = 0xFEFF;
fwrite(&BOM, 1, sizeof(BOM), fp);

it will "do the right thing" regardless of the platform.

similiarly, if you do this:
wchar_t BOM;
fread(&BOM, 1, sizeof(BOM), fp);
if (BOM == 0xFEFF) // don't switch endian
else // switch endian

it will also do the right thing, regardless of platform.
