Yes, it does. The way to enable this depends on your version of Notepad++. On newer versions you can use:

Menu ViewShow Symbol → *Show All Characters`

or

Menu ViewShow SymbolShow White Space and TAB

(Thanks to bers' comment and bkaid's answers below for these updated locations.)


On older versions you can look for:

Menu ViewShow all characters

or

Menu ViewShow White Space and TAB

How to Find Special Characters in Notepad++
May 15, 2026 - A pattern like [^x20-x7E] will flag every non-ASCII character in every matched file under the directory. Results appear in the Search Results panel at the bottom. Each result shows the filename, line number, and the matching line content. Clicking any result jumps directly to that exact line in the file. One practical note: if you run Find in Files without a file filter on a directory that contains binary files (images, compiled executables, PDFs), Notepad++ will scan those too and produce false or meaningless results.

Hidden character in text file

Likely an ASCII character that did not convert correctly. Try using NotePad++ or something non-Microsoft to make sure the CLRF (carriage return, line feed) characters are displaying as expected. Otherwise it could be a control character that is being used for some reason.

What are all the strange characters you see when opening certain file types in notepad?
Different files use different formats. Dll files can be opened using text editors, but they arent text files, and instead contain compiled code which shows as those characters when opened in text editors. dll files use the same file format as executable files, either NE/PE format.

How do I make hidden characters visible in Notepad++ without searching?
Go to View > Show Symbol > Show All Characters. This renders tabs as arrows, spaces as dots, and line endings as pilcrow symbols. It works as a rendering overlay only and does not modify the file.

Click ‘Find Characters in Range” (the last item in the list) 4. Make sure “Non-ASCII Characters (128-255)” is selected (I think it is the default).

r/sysadmin on Reddit: Hidden character in text file
April 26, 2016 -

I'm in the process of reverse engineering some of my company's existing scripts, and after dumping the output into OneNote, I get a little boxed "?" in some of the spaces, indicating a special character.

Now...in notepad this character is nowhere to be seen, however, I do get a little phantom character when scrolling through the text

i.e. To get to the end of

... 

I need to scroll over one of the periods twice, as the cursor does not move the first time you press left/right. Now bear in mind, that this is in notepad, so I didn't think I'd see anything weird in the character department.

It might be worth noting that this is a .sed file. The old sys admin guy installed the .exe ports of all the common Unix commands onto all of our Windows servers and is running this as a cron job..on Windows. Please don't ask.

Any insight would be very much appreciated.

UPDATE#

The hidden character is called a File Separator and is a non visible character used for functions rather than text.

Apparently the script it appears in is what's called a pipe separated value to comma separated value script. It's contents are as follows:

/--- ---/d
s/  */ /g
s/,,/,/g
s/^  *//
s/"/'/g
s/.*/"&/
s/$/"/
s/ /","/g
s/"  */"/g
s/  *"/"/g

If you copy the text the FS hidden character should be in there too. After some research, I found that this is pretty common when taking SQL data and transforming it into raw data, as these Reg Exes strip away any odd spaces, take out any SQL formatting, leaving you with raw text.

So, for the sed command:

| sed -f psv2csv.sed > Outputfile.csv

Where we pipe data in from the SQLCMD, grep the pertinent lines and THEN Sed. The -f specifies that a input script is used for the RegEx.

Maybe you'll find it useful!

February 19, 2020 - Oh, I also meant to say (but got distracted – ooh, squirrel!) that Edit > Character Panel will give the 255 character codes for 8-bit encodings; if you change from one encoding to another, the Character Panel will correctly update to match. It lists both decimal and hexadecimal character codes, along with the character at that point.

When I look in my game install folders many of the file types can be viewed in notepad. For example .dll files. Why are they made up of these alien looking characters? Is it because it’s written using a program that notepad can’t understand or something?

I’m not a programmer obviously but I’ve always wondered about this.

Other examples are bdt files, zdp
