Now I don't understand, sorry. :-)
UTF8String =  type AnsiString(CP_UTF8), is there another string type with 
CP_UTF8? What is the definition of "string" in cpstrnew? AnsiString(CP_ACP)?
http://wiki.freepascal.org/FPC_Unicode_support does not answer the question 
AFAIK.
Hmm, I checked the Lazarus source, it seems I was wrong with the assumption 
that Lazarus uses "UTF8String" everywhere, it uses "String" instead, correct?

Example:
type
  TTranslateString = type String;
  TCaption = TTranslateString;

  TControl = class(TLCLComponent)
[...]
    property Text: TCaption read GetText write SetText;

  TCustomEdit = class(TWinControl)
[...]
    property SelText: String read GetSelText write SetSelText;
