Thanks for your quick feedback!
The problem is not a result of converting:
If you are opening your file in 3.7.1 and then exporting a PC exe from 3.7.1, the text problem is still the same in the exe.
What's interesting: If you add an interface+inventory in your file, the interface text like "walk to" is displayed, even when you export the game to an exe.
So it's not a general problem of the font or displaying text. It's just the character monolog/dialog text which makes trouble.
Adding a completely new character who is talking does not change anything: The monolog text is only displayed in the editor, not in the exported game.
I will delete some code in your file and try to localize where the problem is....but I will need luck, I am an artist, not a coder
