I wanted to explore utf-8 a bit via python3.

I started by writing and running
python3 smiley_raw.py

I cleaned up some unrendered characters by hands

After that I removed all the break lines characters via
tr -d '\n' < smiley_raw.txt > smileys.txt

And here is final result

Also, I did notice two packs of 12 clock icons, so I decide to animate them a bit. Just run
python3 clock.py
and you should see something similar to this
