Arabic and H5P

Hi!

My name is Anna and I am a teacher of Arabic language. I have been trying using H5P for creating some activities but it gives me different problems when using Arabic script: 

- Letters appear too small and I can't find the way to make them bigger.

- Text keeps appearing on the left instead of being on the right

- When I need to add symbols (just like parenthesis, hyphens, numbers, stars...) text just gets crazy and mixed.

Is there a way to solev it?

Thanks!
