EU4dll VS Playlunky

Here. You'd also need a double byte patch, an injected dll that let the game reparse text since old pdx titles don't support Unicode.

The game I like does not support encodings other than ASCII, so I need to inject via DLL to apply a localization patch in my native language. Thanks in advance!

In some/most/all(I'm not sure) places, the game can only display characters which are in the Windows-1252 character set(AKA ANSI). The localisation files can contain UTF-8 characters, but I'm not sure in which location the game can display them. Some translation mods need the user to modify/patch eu4 so that it can use UTF-8 in more places(for example the chinese language mod needs https://github.com/matanki-saito/EU4dll )

Sry, was a bit short earlier because I really wanted breakfast. Basically you are trying to pack mods, which has long been unsupported. I am sure you use the latest version of Modlunky and you see the big warning at the very top. Even while it was still supported as the major way to mod the game, the overrides folder was not the supported way to make mods. So there are so many layers of wrong here. If you don't have it already, get the latest version of Modlunky. Then the instructions above will work. Check the wiki for Playlunky if anything is unclear (that also lists supported audio formats).

There's nothing wrong with a little reading. The documentation on Playlunky gives all the steps you need (linked below). https://github.com/spelunky-fyi/Playlunky/wiki If you have a significant issue with anything other than a video, you'll probably just have to find another human to show you what to do. It's easy though, so you can probably figure it out.
