The issue is indeed the conversion from UnicodeString to WideString
which is not allowed for a var/out parameter. That the compiler doesn't
use the error “Call by var for arg no. 3 has to match exactly: Got
"UnicodeString" expected "WideString"” is due to Ansi2WideMoveProc()
being a function pointer. The code that determines that error is not
called in that case, instead the other is caused essentially as a last
resort.
