Note that if your primary concern is emojis in prompts (rather than in
text typed as command input), zsh has the %G (for "glitch") prompt
sequence.  So if you write e.g.

PS1="Cloudy %{☁️%2G%}% "

then zsh will correctly reserve 2 positions for the glyph when
calculating the prompt. (Note gmail may have messed up the copy-paste
of the emoji; do it right and it works).
