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...
