I found this article which I recommend all the developers to go through
“In general, your safest bets are just to use the system default which will usually be an easy-to-read sans-serif font that the user of any system should be familiar with; or to use your own custom font so you have precise control over what the user will see.”
I believe rather than changing the font style, it is better to add double spaces at the end of the word.
As this will give the users the best readable font style by default. (As we cannot use San Francisco, Sans-serif, Arial in our react-native projects because they are copyrighted and not open-sourced).
