If the BOM is missing and it is not UTF-8, it isn't a valid UTF 
encoding.

Otherwise you have your answer. Don't cast a char[] to wchar[], 
if you have a valid char[] then it must be converted (use 
std.conv.to);

Some testing, the mentioned check for UTF-16 being even is 
exactly what caused the "array cast misalignment" error (the 
array wasn't an even number of bytes).
