The problem is that by default in Windows stdout is opened in 7 bits
mode (text), this means that writeln when emits some information in
UTF8 with any char >127 will enter in some kind of error reported from
rtl or Windows kernel.

I do not know how to inform the fpc to "reopen" the stdout handle in
binary mode, but you can "hack it" by (at least for tests):

uses classes,windows;

 s: string;
 OutputStream: TStream;
 Writeln('code page UTF8 - 65001 en Windows');
 OutputStream := THandleStream.Create(GetStdHandle(STD_OUTPUT_HANDLE));
