BTW, in this context - can users choose UTF16BE on little endian 
platforms (and vice versa)? In other words - do the respective 
UnicodeStringManager routines have to check the source/target 
endiannes in the respective field of the header when performing 
conversion between AnsiStrings and UnicodeStrings?

Not that the current implementations for Unix or Windows would seem 
to worry about this, but I'd prefer to know (and preferably have 
documented ;-) ) whether it's an omission or intention based on an 
explicitly defined rule...
