A *dynamic* encoding *never* can be CP_ACP nor CP_NONE (in Delphi). 
These values are allowed only for *static* types in type declarations.
CP_UTF16 is also not allowed.

Delphi StringCodePage reports the current default codepage 
(DefaultSystemCodePage) for empty AnsiStrings, CP_UTF16 for all 
UnicodeStrings.

The same for CP_ACP.
