I'm writing an ftp server by using TIdFTPServer.
It shows unicode directory and filename correctly under Windows.
But It doesn't show that under linux.
I had trace indy ftp server codes for several days, such as Setp in debugging, snipper data packets by wireshark.
FINALLY! I found a solution!

In IdFTPServer, procedure TIdFTPServer.DoDataChannelOperation
about line 3686:
      if AContext.FDataChannel.FDataChannel.IOHandler.Connected then begin
        AContext.FDataChannel.FDataChannel.IOHandler.WriteLn(ASrcStrings[i], LEncoding);
change to :
      if AContext.FDataChannel.FDataChannel.IOHandler.Connected then begin
{$IFDEF WINDOWS}
        AContext.FDataChannel.FDataChannel.IOHandler.WriteLn(ASrcStrings[i], LEncoding);
{$ELSE}
        AContext.FDataChannel.FDataChannel.IOHandler.WriteLn(ASrcStrings[i], LEncoding, LEncoding);
{$ENDIF}
It works PERFECTLY!

Fix more unicode bugs:

In IdFTPServer, find procedure TIdFTPServer.DoConnect(AContext: TIdContext);
AContext.Connection.IOHandler.DefStringEncoding := IndyTextEncoding_8Bit;
change to:
AContext.Connection.IOHandler.DefStringEncoding := IndyTextEncoding_OSDefault;

In IdCommandHandlers, find procedure TIdCommand.SendReply;
Context.Connection.IOHandler.Write(Reply.FormattedReply);
change to:
{$IFDEF WINDOWS}
  Context.Connection.IOHandler.Write(Reply.FormattedReply, false, IndyTextEncoding_UTF8, IndyTextEncoding_OSDefault);
{$ELSE}
  Context.Connection.IOHandler.Write(Reply.FormattedReply, false, IndyTextEncoding_UTF8, IndyTextEncoding_UTF8);
{$ENDIF}

And there is last bug for change directory while name contains unicode chars, wait for me updating later.

In IdCommandHandlers , find procedure TIdCommandHandler.DoCommand(const AData: string; AContext: TIdContext; AUnparsedParams: string);
    LCommand.FRawLine := AData;
    LCommand.FContext := AContext;
    LCommand.FUnparsedParams := AUnparsedParams;
change to:
{$IFDEF WINDOWS}
    LCommand.FRawLine := UTF8decode(AData);
{$ELSE}
    LCommand.FRawLine := AData;
{$ENDIF}
    LCommand.FContext := AContext;
{$IFDEF WINDOWS}
    LCommand.FUnparsedParams := UTF8decode(AUnparsedParams);
{$ELSE}
    LCommand.FUnparsedParams := AUnparsedParams;
{$ENDIF}


Now, it solved all of unicode bugs for multiplatform.
I've tested on windows x86 and linux x64

Additional, there is part of an example of idftpserver implementation.
procedure FtpServerOnRemoveDirectory(ASender: TIdFTPServerContext;
  var VDirectory: TIdFTPFileName);
var
  tmpPath: string;
begin
  tmpPath := TrimFilename(BASE_PATH +
    PathDelim + VDirectory + PathDelim);
{$IFDEF WINDOWS}
  tmpPath := UTF8encode(tmpPath);
{$ENDIF}
  if DirectoryExistsUTF8(tmpPath) then
  begin
    RemoveDirUTF8(tmpPath);
  end;
end;             
  
procedure FtpServerOnListDirectory(ASender: TIdFTPServerContext;
  const APath: TIdFTPFileName; ADirectoryListing: TIdFTPListOutput;
  const ACmd: string; const ASwitches: string);
var
  Sr: TSearchRec;
  tmpPath: string;
begin
{$IFDEF WINDOWS}
  tmpPath := TrimFilename(BASE_PATH +
    PathDelim + SysToUTF8(APath) + PathDelim + '*');
{$ELSE}
  tmpPath := TrimFilename(BASE_PATH +
    PathDelim + APath + PathDelim + '*');
{$ENDIF}
  if FindFirstUTF8(tmpPath, faArchive or faDirectory, Sr) = 0 then
  begin
    repeat
      if (Sr.Name <> '.') and (Sr.Name <> '..') then
      begin
        with aDirectoryListing.Add do
        begin
          if (Sr.Attr and faDirectory) = faDirectory then
          begin
            ItemType := ditDirectory;
          end
          else
          begin
            ItemType := ditFile;
          end;
          FileName := Sr.Name;
          Size := Sr.Size;
          ModifiedDate := FileDateToDateTime(Sr.Time);
          // do your jobs 
        end;
      end;
    until FindNextUTF8(sr) <> 0;
  end;
  FindCloseUTF8(sr);
end;

OnChangeDirectory needn't consider converting encoding in implementation, cause there is no interaction with file system.
Other events are similar to OnRemoveDirectory, just convert encoding under Windows.
