Keybase proof

I hereby claim:

• I am barend on github.
• I am barend (https://keybase.io/barend) on keybase.

To claim this, I am signing this object:

The following is the Black Female Astronaut emoji as encoded
in UTF8, shown in hex:

F0 9F 91 A9 F0 9F 8F BF E2 80 8D F0 9F 9A 80   byte value
 1  2  3  4  5  6  7  8  9  0  1  2  3  4  5   byte number

As you can tell it's fifteen bytes. If you express the hex
digits in binary you can see how UTF8 encoding works, and
you can see it's made up of four characters.
