[edk2-UDK2017] issue about AsciiPrint

[krishnaLee <sssky307@163.com>]

Hi All,

This function will output nothing or strange-output in my real Lenovo_Q270 machine, follow is the key point:


//for(UINTN j=0;j<sizeof(RSDP->Signature);j++)
//{
                        //output byte by byte,or custom range...,or just some specified bytes in the string... 

//AsciiPrint("%c",j,SignatureStr[j]);
//}
------------------------------------------------------------------------------------------
I had read the Print function note,but I don't understand  its meaning for ascii string using AsciiPrint, for example:If someone want print a part of ascii-string byte by byte...,
I am newer to write uefi code,May be I mis-understand it,Can anybody clarify it ,or give the full instruction about AsciiPrint.
type:
%
Print a %%.
c
The argument is a Unicode      character. ASCII characters can be printed using this type too by      making sure bits 8..15 of the argument are set to 0.




attachment is the full test code.
