In Delphi (and FPC) CP_ACP corresponds by default with the current system codepage (e.g. CP1252 on a German Windows).
OK. So in Delphi XE (in Germany) String(CP_ACP) is the same as String(CP1252) but different from String without brackets which in turn is the same as String(CP_UTF16) ? Correct ?
CP_UTF16 is not supported, because AnsiString only supports 1-Byte character strings (and UTF-8 as the odd one) and not 2-Byte character strings.
I still don't understand. The wiki article seems to suggest that it is about a type called "ANSIString" that features a dynamically settable "code page information". From discussions about Delphi and FPC, I only know a String type with a dynamically settable "code page information" that also features a dynamically settable "Bytes per Character information" and hence does support 1, 2 and 4 "Bytes per Character". (e.g. UTF-8, UTF-16, and UTF-32).
The difference to Delphi currently is that for FPC String=AnsiString(CP_ACP) and for Delphi String=UnicodeString (aka 2-Byte string).
I understand that you mean (e.g.) Delphi XE. But what version of FPC is "currently". Am I wrong assuming that in the svn we do have the "NewStrings" library that supports dynamical code-page *and* byte-per-character settings and hence supports e.g. CP1251, UTF-8, UTF-16, and UTF-32 ? So I seem to understand the meaning of String(CP1252), String(CP_UTF8), and String(CP_UTF16) (which seems do be the Delphi notation), but I seemingly don't get the exact meaning of "AnsiString(CP_ACP)" or "AnsiString(CP1251)"
In the end, what the definition of "String" without brackets is, might be due to a settable compiler option and/or the OS the compiler is set to create code for.
