Removing “NUL” characters

Question

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

What i want to do, is replace those null, to be nothing, so i can copy my whole line. Maybe there is any keyword that will tell notepad++(or any other program that might help) to replace those characters? When i am selecting it, use Right Click and then "clear", its gone - but i dont want to do it one by one.

I don't care about removing the cause of this problem, just the effect(NULs)

Answer 1

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.

Answer 2

Click Search --> Replace --> Find What: \0 Replace with: "empty" Search mode: Extended --> Replace all

Answer 3

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

Answer 4

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.

Answer 5

I tried to use the \x00 and it didn't work for me when using C# and Regex. I had success with the following:

//The hexidecimal 0x0 is the null character  
mystring.Contains(Convert.ToChar(0x0).ToString() );  

// This will replace the character
mystring = mystring.Replace(Convert.ToChar(0x0).ToString(), "");  

Answer 6

I was having same problem. The above put me on the right track but was not quite correct in my case. What did work was closely related:

• Open your file in Notepad++
• Type Control-A (select all)
• Type Control-H (replace)
• In 'Find What' type '\x00'
• In 'Replace With' leave BLANK
• In 'Search Mode' Selected 'Extended'
• Then Click on 'Replace All'
