I'm trying to publish a demo game to itch.io in the HTML5 format, but when tested, the game doesn't load and says me this:

There was a problem loading your project:

Archive contains filename with non UTF-8 Encoded characters

Please try deleting the ZIP file and uploading another one.

I just don't know what to do.

Your game probably has a file with an accented letter in the name. Just rename it to something else.

MrQuickGame, how did you remove that mistake? Help please
