What is the text encoding of realtime database

[Alban Le Goff]

Hello, as part of my studies, I am doing the pictionnary game.
The one who draws sends the drawing to the firebase realtime database.
The image is a vector image composed of points.
I want to reduce the size of the drawings as much as possible since there is a download limit of 10go/month with firebase.
I will need to know what text encoding is used by realtime database.

Thank you for your attention,
Alban Le Goff

The Realtime Database uses UTF-8 for all it's encoding internally and in it's API.

Thanks for your answer. Do you know what happens if I exceed the 10g/month download limit? Will the flow be slowed down or will I not have access to the database anymore?
