Support for Extension F

[via Unicode]

Dear All,

As many of you are aware getting characters encoded is only half the 
battle, enabling people to use them is the other half.

CJK Extenion F was added last year in Unicode 10. I have come across a 
number of people saying they are having problems with Ext F. I was 
wondering what the current support is for Ext F at OS level and in terms 
of fonts.
