Since the Unicode BOM is a set of code points like any other, 
they can be expressed in UTF-8. There are the occasional text 
files that have a BOM even though they are encoded as UTF-8. I 
feel that readText is too strict in that case. It should just 
silently ignore the BOM and continue because it is just 
meaningless. Throwing an exception seems completely wrong to me.
