Can I risk trimming international characters when I include includeFontPadding in false?

To get rid of the extra space on top of the TextView, I have a solution to set the property includeFontPaddingto false.

The project must be internationalized in many languages, including Chinese, Japanese and other non-Latin scripts. Is the includeFontPaddingreserved space guaranteed to be empty, or do I risk trimming any tall characters by setting the property to false?
