No. That one has nothing to do with any Widestring manager, but with the 
memory manager. The purpose of the widestring manager is to convert from 
strings of one encoding to another encoding.

Please note that on Windows WideStrings will work across DLL boundaries, 
because they are managed by Windows. This is not the case on other 
targets though as there WideString = UnicodeString and UnicodeStrings 
have the same restrictions as AnsiString.
