How can I replace characters on the hexadecimal level in Notepad++?

I have a file with some characters that can not be displayed in UTF-8 (problem with ANSI to UTF-8 conversion) and would like to replace these with the correct characters.

Notepad++ replace (Ctrl + H) can not distinguish these characters.

Does Notepad++ have a hex mode?

Using the hex editor notepad++ Step 3 – Open any .exe file; In the image below, I have opened the Notepad++ setup in hex format. Once the file is opened, click on Plugins, then HEX-Editor and click on “View in HEX” like below and Your encoded Text will be converted to Hex.

You can use a hexadecimal code to find and replace in the Find dialog box, with Search Mode is set to Regular expression. Use the following search expressions as an example:

Find what: \x{0A} # Finds a line feed

Find what: \x{0D} # Finds a carriage return
