2020年3月31日 · This format makes use of 8-bit characters, and terminates the string with a NUL character. The string is immediately visible in the file, as shown below - note the terminating NUL. 2. UTF-16. This format makes use of 16-bit characters (i.e: two bytes concatenated), and can represent a portion of the code points described by Unicode.

2016年5月2日 · Normal text editors such as Notepad usually do not have the capability to enter NUL characters into files. What you probably want to do is to use a "hex editor" (some text editors also have a "hex" mode). This will let you enter NUL characters, or any other byte you might need.

A hackish way to replace given character/characters with NUL is via the Hex Editor Plugin †. Go to hex mode (via Plugins → HEX-Editor → View in HEX, or Ctrl + Alt + Shift + H ) Highlight the character(s) you want to replace.

Update: What I ...

Would it be accurate to interpret that prior description to mean "a control character or non-printing character is a code point (a number) in a character set, that does not represent a written ASCII symbol."

RFC 20 ASCII format for Network Interchange provides a description of the proposed control codes and their function. For instance here is a partial list from section 5.2 control codes of RFC20: NUL (Null): The all-zeros character which may serve to accomplish time fill and media fill.

2012年11月17日 · It's how some programs display the NUL character—ASCII value 0, also known as \0 in C. Here I've created a file with a NUL byte in it. † Notice that I use cat -v to show non-printing characters. $ cat -v blah hello null^@ hi $ hexdump -C blah 00000000 68 65 6c 6c 6f 0a 6e 75 6c 6c 00 0a 68 69 0a |hello.null..hi.| 0000000f

2022年1月14日 · Integer value zero, sometimes referred to as the ASCII NUL character. Characters whose integer representations are in the range from 1 through 31, except for alternate data streams where these characters are allowed.
