Hello! I have changed my PROMPT variable for bash and zsh in the following:
TRIANGLE=$'\uE0B0'
COLOR_1="#089B89"
COLOR_2="#FCFCFC"
COLOR_3="#3B4045"
PROMPT="%K{$COLOR_1} %n@%M%F{$COLOR_1}%K{$COLOR_2}$TRIANGLE%F{$COLOR_1} %~%F{$COLOR_2}%K{$COLOR_3}$TRIANGLE%f%k " #%K{#1BA58A}%F{black}$TRIANGLE
and I’m using the Noto Sans Mono fonts, but this happens on other fonts as well.
How can I get rid of the white lines before the triangle? should I use a specific font?
Have you tried with the Nerd Fonts?

Noto Nerd will contain Noto Sans/Serif/Mono etc. Notably it’s hard to ctrl+f on that page since most of them don’t have text names, so just scroll to ‘N’.
