How to delete <0x00> characters in Sublime Text 3?

Question

Problem

So I have this large text file which contains <0x00> characters (see picture below).

As you can see on the picture above, I have tryed to remove those characters with a regular expression \x00. Besides that, I have also tryed \0 and \00 with no success.

However, when I try to replace these characters in Sublime Text, a pop-up shows that these <0x00> characters indeed have been found (see picture below), so far so good.

Unfortunately, when I click the "replace" button the characters are not replaced.

Question

How can I get rid of these <0x00> characters?

p.s. It is important to mention that I cannot do a search on "0" since this text file contains zero's, which I would like to remain.

Progress update #1

I have managed to copy a <0x00> char into the "find" search box (see picture below).

However, even when I try to replace this character with an empty character inside the text file no changes occur unfortunately.

Progress update #2 (solution)

Without the helping hand of @00 I wouldn't find the answer to this problem, thank you!

Explanation

The file was encoded in UTF-16, but I assumed it was UTF-8. The file was opened in BOM UTF-8, which was exactly the reason why I was not able to delete the <0x00> (NUL) characters in Sublime Text 3.

Solution

Execute in 'bash' or in a 'terminal' the following command:

sed -i 's/\x0//g' [textfile_name].txt

Answer 1

Ok, I've tried this out myself and it seems that a regular expressions will work. Make sure you have the regex option selection (highlighted in image) and use a regex of \0:

Now just make sure you have nothing in the replace filed and hit Replace All. The NUL characters should be gone.

NOTE

While reading around, it seems that you have a NUL after every other character which might indicate that the file is actually UTF-16 (and if this is the case, you do not want to remove them) and would need to be reloaded as such. If switching to UTF-16 and my above solution do not work, this thread may be of use to you.
