remove NUL

[darknkreepy3#]

I opened a backup .bk of a bootcode file to look around and see what was in it with notepad++. There were a lot of

/x00
NUL characters

But I could not remove them with that even with a simple expression. So I used this to FIND and REPLACE with a

/n
newline character

Code: Select all

(?!\t|\r|\n)[\x00-\x1f]

Which as you can see removes all of these hexadecimal characters

\xff Matches ASCII hexadecimal character ff.
