Well, I've tried to look for a solution but I didn't find it.
The error works this way: I use Wamp as a server, let's say that I'm working today in a project, I do my tasks and tomorrow or when I close wamp and I open it again with the rute of my project, there are a lot of strange or weird symbols, like this: ��l͛�S�iy�r�O7����%L]�.
At the beginning, I thought that I was Visual Studio Code because I've downloaded many pluggins. Ok, I did that and it was still happening...
Then, I uninstalled WampServer but it still happens! I'm using wordpress for a website and is annoying... I must delete the project, again. And I don't know what to do.
Yesterday I had the website looking good, using: localhost/wordpress. But today that I turned my laptop on, I can't even use wordpress. It doesn't say any message about the error, just shows a lot of strange symbols.
I work with utf-8 for spanish symbols, I'm not sure if is that. But look, I leave you a image of how it shows on my screen:
