I just did some rendering with this exact same font.

Try FT_Select_Size with an index into the available-sizes table
instead. Since Noto Color Emoji only comes in one size, an index of 0
should work.

In my example
<https://github.com/ldo/harfpy_examples/blob/master/region-flags>, I
found it easier to use a graphics engine like Cairo to take care of the
font-sizing headaches for me.
