Technically speaking, the list of available emoticon entries (in the
mail composer menu) is hardcoded in a source code file:
https://git.gnome.org/browse/evolution/tree/src/e-util/e-emoticon-chooser.c#n36

In plain text mode the corresponding Unicode character is inserted.
Which is the third item in each row in that source code file.

In HTML mode the corresponding icon gets loaded (from the theme your
desktop environment is set to). Which is the second item in each row. 
So for "face-smile" using the Adwaita icon theme,
https://git.gnome.org/browse/adwaita-icon-theme/plain/Adwaita/256x256/emotes/face-smile.png
gets inserted from the list of icons you can see at
https://git.gnome.org/browse/adwaita-icon-theme/tree/Adwaita/256x256/emotes

(Some developer feel free to correct my interpretation of code.)

Cheers,
andre
