Length needs to be fixed. I know about the bug but had not looked at it yet.

AnsiString has code page assigned to current system encoding. You can 
change it though using SetMultiByteConversionCodePage routine. 
RawByteString has no encoding. Therefore assigning to AnsiString 
converts right operand to AnsiString encoding first. Assigning to 
RawByteString does not invoke any conversion and as result of assigning 
RawByteString left operand will get the encoding or right operand.
