So it has no alternative but to make the line's height larger. Interesting. I based my expectation on the built-in Terminal application on macOS. It uses the same default font as Emacs, yet emojis do not change the height of its lines. > The only solution to that could be if you configure the fonts > installed on your system to have a font which supports Emoji and whose > height is not larger than that of the font used for the default face. Cannot Emacs, when defaulting to "Apple Color Emoji", make the emojis a bit smaller?
