I have got characters like that in my notepad++
When i am trying to copy whole line, i am actually copying everything until \"NUL\":
File:1
Highlight a single null character, goto find replace - it usually automatically inserts the highlighted text into the find box. Enter a space into or leave blank the replace box.
Click Search --> Replace --> Find What: \0 Replace with: "empty" Search mode: Extended --> Replace all
This might help, I used to fi my files like this: http://security102.blogspot.ru/2010/04/findreplace-of-nul-objects-in-notepad.html
Basically you need to replace \x00 characters with regular expressions
Try Find and Replace. type \x00 in Find text box, check the Regular expression option. Leave Replace textbox blank and click on replace all. short cut key for find and replace is ctrl+H.
Open Notepad++
Select Replace (Ctrl/H)
Find what: \x00
Replace with:
Click on radio button Regular expression
Click on Replace All
