I suggest doing this while Notepad++ itself is not running. If it does not, you can try downloading the zip file from here and put its contents (it's one file called NppTextFX.dll) inside the plugins folder where Notepad++ is installed. (I can confirm seeing 'TextFX Characters' in the Available tab in Plugin Manager.) It should usually work using the method Dave described in his answer. It was removed from the default installation as it caused issues with certain configurations, and there's no maintainer.

Plugins -> Plugin Manager -> Show Plugin Manager -> Available tab -> TextFX Characters -> Install. As per the author, the code behind this binary is found on this branch. If you run into any, feel free to raise a GitHub ticket for each, as the author (HQJaTu) is recommending. Now inside the Plugins Admin window, click on Available (from the horizontal menu) and then navigate to the Search bar in order to locate the Plugin you wanted to install. You will need to create the NppTextFX directory first though.Īs per this GitHub issue, there might be some bugs lurking around. Firstly, launch Notepad++, navigate to the top horizontal menu, click on Plugins and then select Plugins Admin from the sub-menu. You can download the DLL from here, drop it under Notepad++/plugins/NppTextFX directory and restart Notepad++. There is an unreleased 64-bit version of this plugin.
