+The original bug is fixed: My array of strings is being passed as
+unicode.  However, I have another array of strings that I would like
+to pass as ansi.  So I have defined it like:
+
+[DllImport("nsrchcsw", CharSet = CharSet.Unicode, CallingConvention =
+CallingConvention.Cdecl)]
+
+public static extern void nativeQFIndexerCreateIndex(long nsAddress,
+[MarshalAs(UnmanagedType.LPArray, ArraySubType=UnmanagedType.LPStr)] 
+string[] cmdArray, int count);
+
+
+It is now always passing it as Unicode.  Should I beable to define the
+marshalling in this way?  I can work around this: I will just convert
+the Unicode to ansi in my unmanaged code.
+
+One other problem. Which I think is the same problem just in the other
+direction.  I now have unmanaged code that is calling a delegated
+function in my managed code. I am sending unicode strings (defined as
+unsigned short* string - this is not an array of strings in this
+case).  Once the string is passed to my managed code it is truncated
+to the first character.
+
+The bytes in my unmanaged code look like: t,0,i,0,t,0,l,0,e,0,0,0
+I get t,0 in my managed code.
+
+Is it thinking the strings are UTF-8 not Unicode?
