The CJK F block is displayed on the wikipedia page CJK Unified Ideographs Extension F:
I've tried updating Babel Han but they themselves say:
Characters / Percentage
CJK Unified Ideographs Extension F 1,141 / 7,473 15.3%
So, only fifteen percent of Extension F characters are covered in Babel Han.
Hanazono hasn't been updated in a while and only supports up to Extension E.
How can I display the CJK Extension F block in my browser?
