Hi Muhammad,
Thank you for posting your query in our community.
Based on your description, when you enter letters which is in Bengali language on OneNote, it will have some problem.
May I confirm that whether you are using the latest version of Office applications? If not, please update to the latest one to check if the problem persists.
To check whether the problem is related to OneNote on Android device, could you please try to enter the same letters in other Office applications on Android to see the results?
And if possible, could you please enter the same letters on other device, such as: PC, Mac, to see if the problem happens as well?
Appreciate your cooperation in advance.
Best regards,
Jazlyn
