Cannot write the space character in notebook title #1

every time i press space when changing the title (in the top left), the game crashes. though when i come back to the game the notebook has been created (but without the space of course)

here is my crash report (with the example "Test ")

The game crashed: rendering screen Error: java.lang.RuntimeException: java.io.FileNotFoundException: Notebook\Test \0.notebookpage (The system cannot find the path specified)
