As far as I’ve been able to find, this is a discourse feature to allow easily pick an emoji when you don’t have an emoji selector on your keyboard
That’s why depending on how the poster created the emoji, you will see the unicode (probably someone with a keyboard emoji picker) or the shortcode (using the discourse emoji picker).
How is this conversion affecting you negatively? On emails they should be converted into the unicode one.
