Method matchFamilyStyleCharacter

shared/java/FontMgr.java:108–116

Use the system fallback to find a typeface for the given character. Note that bcp47 is a combination of ISO 639, 15924, and 3166-1 codes, so it is fine to just pass a ISO 639 here. Will return null if no family can be found for the character in the system fallback. Passing `null` as the parameter

     * requested character will be matched.
