Andrew Fish,
thank you,in this case,you are right.
but I think there may be other case that the user data just contain some nosense-data
such as { UINT16 MyData[]={0x000c,0x000d,0x000d,0x000e}  } to the editor, 
the uefi editor may also meet this question,the editor may do not need output this,
but the editor should make sure other visible chars can output normal...


I don't know if it is a bug or not.


Thank you very much.
krishna.

Krishna,


Your log.txt looks like a normal UTF-16 Unicode file. The leading  FF FE is the Byte order mark for UTF-16 Little Endian [1].  The file looks like it has CR line endings [2] so maybe that is confusing your editor? There seems to be a CR LF at the end, so the mixture of line ending may even be more likely confusing the editor. The byte order mark should let your editor know it is 16-bit Unicode and the correct endian. Hope this helps...

Krishna,

From an EFI point of view BackSpace 0x08, LF 0x0A, and CR 0xD are defined for a ConOut device. 

From Ascii Control Codes:
0x0C - Form Feed
0x0E - Shift Out

The Shift Out is used with graphics characters. 

How did you dump the log? If EFI sends data to a serial terminal then it would use terminal emulation and the output stream would look different. 

Thanks,

Andrew Fish

Andrew Fish,
Yes,I know it ,from a terminal's view,the 0x0C/0x0D/0x0E/...,some invisible chars like this have special means,
and I also think from a text-editor's view, I think the text-editor just do not show them,and should make sure all visible chars can visible,
but I think I am wrong.


> How did you dump the log?
I got a piece of buffer from uefi-shell's screen-buffer,when I output my buffer,I find it is not correctly aligned as history output.
because the screen-buffer's width is 'terminal_column_size + 2',the last extra two UINT16 maked this question,
I think when the terminal output a full line(terminal_column_size),it will automatically go to new line's begin,
CR is means go to most left corner of screen,,so I make the last two char with "CR+CR",the cursor will stay at the new line's begin;
and make the (CHAR16==0) to (CHAR16==SPACE),so all lines are (full line+CR+CR),except last line end is (CR+LF),
 and the result is aligned as the history showed.
but some times the result is missed some strings...


I may got what happened,the question is "...make the (CHAR16==0) to (CHAR16==SPACE),so all lines are (full line+CR+CR)"&#65533;&#65533;
the lines may not all full line because some invisible will taken no space in terminal,it is not a full line,so CR+CR will make the line overlapped/disappeared.
I had mixed using text-editor's view and terminal's view in uefi,it's my fault.
I can duplicate this fault by follow test code:
//test-code-start
EFI_STATUS
EFIAPI
UefiMain (
  IN EFI_HANDLE        ImageHandle,
  IN EFI_SYSTEM_TABLE  *SystemTable
  )
{
  EFI_STATUS status;
  EFI_SHELL_PROTOCOL*                     shell;
  EFI_SHELL_PARAMETERS_PROTOCOL*          param;
#defineONE_LINE (100+2)
  CHAR16 buffer[ONE_LINE];
  UINTN bufferSize = ONE_LINE *sizeof(CHAR16);


for(UINTN i=0;i<ONE_LINE;i++)
  {
    buffer[i]=0x0020;
  }


  buffer[ONE_LINE-8]=L'a';
  buffer[ONE_LINE-7]=L'b';
  buffer[ONE_LINE-6]=L'c';


  buffer[ONE_LINE-4]=L'O';
  buffer[ONE_LINE-3]=L'K';
  buffer[ONE_LINE-2]=0x000D;
  buffer[ONE_LINE-1]=0x000A;


  status=gBS->LocateProtocol(&gEfiShellProtocolGuid,NULL,&(shell));
if(status!=EFI_SUCCESS)
  {
return0;
  }


  status=gBS->HandleProtocol(gImageHandle,&gEfiShellParametersProtocolGuid,&(param));
if(status!=EFI_SUCCESS)
  {
return0;
  }


Print(L"test1:\n");
  shell->WriteFile(param->StdOut,&bufferSize,buffer);
  shell->FlushFile(param->StdOut);


Print(L"test2:\n");
  buffer[ONE_LINE-9]=0x000D;
  buffer[ONE_LINE-5]=0x000D;
  shell->WriteFile(param->StdOut,&bufferSize,buffer);
  shell->FlushFile(param->StdOut);


return EFI_SUCCESS;
}
//test-code-end
thank you,
krishna.

Krishna,


From an EFI point of view BackSpace 0x08, LF 0x0A, and CR 0xD are defined for a ConOut device. 


From Ascii Control Codes:
0x0C - Form Feed
0x0E - Shift Out


The Shift Out is used with graphics characters. 


How did you dump the log? If EFI sends data to a serial terminal then it would use terminal emulation and the output stream would look different. 


Thanks,


Andrew Fish

Andrew Fish,
thank you,in this case,you are right.
but I think there may be other case that the user data just contain some nosense-data
such as { UINT16 MyData[]={0x000c,0x000d,0x000d,0x000e}  } to the editor, 
the uefi editor may also meet this question,the editor may do not need output this,
but the editor should make sure other visible chars can output normal...


I don't know if it is a bug or not.


Thank you very much.
krishna.

Hi,
I dumped a small log.txt from my work,but the log.txt showed in uefi shell,is not the same as it showed in notepad++.
I had upload the log here:
https://github.com/krishna116/test/blob/master/log.zip


it seems the log showed in uefi shell had missed some strings...I don't know why,please help,




Krishna,


Your log.txt looks like a normal UTF-16 Unicode file. The leading  FF FE is the Byte order mark for UTF-16 Little Endian [1].  The file looks like it has CR line endings [2] so maybe that is confusing your editor? There seems to be a CR LF at the end, so the mixture of line ending may even be more likely confusing the editor. The byte order mark should let your editor know it is 16-bit Unicode and the correct endian. Hope this helps...
