The Typeface.weight is not a weight of the underlying font file. It is a display style. On older APIs, the display style is adjusted if the Typeface is created from single font. However, after moving to CustomFallbackBuilder, that adjustment is removed since it can crate Typeface from multiple style font files.

Looks like it is good to set display style by ResourcesCompat.getFont for backward compatibility.
