For the "not impressed" one, the unamused one comes pretty close: https://emojipedia.org/unamused-face/

You should put together a request to the unicode consortium - http://unicode.org/emoji/selection.html

There is a good 99% Invisible episode about adding "Person in the lotus position" and "person with headscarf" if you'd like to know more about the process. The reporter only wanted to document the process but ended up submitting a proposal to the Unicode consortium for "Person in the Lotus Position."

On a related note here is a proposal for a recent update to the animal emoji set. It's interesting to see the factors they consider when choosing whether or not to integrate a new emoji. I didn't know that much thought went into what they chose.

I basically want all the old Yahoo Messenger smileys, updated for higher resolution displays: https://usefulshortcuts.com/yahoo-messenger/smileys-emoticon...

We have a billion emojis yet we're missing some of the basic ones...

Those were great, the hug for example is so much better.

Actually, you don't. See the bit on "zero width joiners" in this article. https://blog.emojipedia.org/fun-emoji-hacks/ That's how skin tone and gender are applied in many cases.

For not impressed I use one of these four:

- https://emojipedia.org/neutral-face/

- https://emojipedia.org/expressionless-face/

- https://emojipedia.org/unamused-face/

- https://emojipedia.org/face-with-one-eyebrow-raised/

For hypocritical smile I use this one:

- https://emojipedia.org/grimacing-face/

Obviously context shapes how these emojis are interpreted, but I find they hit the mark for those two expressions.

Scroll down, and look how your choice for hypocritical smile is drawn on Messenger or LG. Not a hypocritical smile at all.
