Is there even something like "current encoding for 'ansistring'" in FPC
3.0? AFAIK FPC 3.0 AnsiString can handle all encodings and convert
between them internally. By default TEncoding output could be set to
AnsiString(CP_UTF8). Conversion to other codepages of AnsiString is done
by the compiler.
OK.
So what is the encoding argument supposed to do ?
- Convert to current codepage (as set in
http://www.freepascal.org/docs-html/rtl/system/defaultsystemcodepage.html
) with possible loss of characters during read ?
- Keep all strings in the codepage that was passed on ?
I see now that FPC's TEncoding uses UnicodeString and PUnicodeChar. For
me it's a strange decision. I would expect it to be String (
http://wiki.freepascal.org/Character_and_string_types#String ) and use
UTF8 since AnsiString(CP_UTF8) is compatible to String.
AFAIK It is Delphi compatible, and there it is unicodestring (well, widestring).
Michael.
