Prompt gap is shorter than it should be

Any idea why this seems to happen on Mac? (misaligned right side frame) Tried it with Terminal and iTerm.

I'll need more information to debug this. Please post the output of the following command.

typeset -m 'POWERLEVEL9K_*|ZSH_VERSION|COLUMNS|ZLE_RPROMPT_INDENT'

For some reason macOS thinks that U+F878 has zero width. This isn't a font issue but some kind of low level bug. You can see it by running the following code:

echo '123\n\uF878^'

In the output, ^ must point at 2 with any font. But on macOS it always points at 1.

Here's another test. If you run this command, you'll notice that the cursor is at the left margin.

PROMPT=$'\uF878' zsh -f

You can work around this issue like this:

POWERLEVEL9K_CONTEXT_TEMPLATE='\uf2be%n%246F @ \uf878%{ %} %180F%m'
POWERLEVEL9K_CONTEXT_ROOT_TEMPLATE='\uf2be%n%246F @ \uf878%{ %} %227F%m'

(I added %{ %} after \uf878.)

You should apply this workaround only on macOS. If you apply it where it's unnecessary, your prompt line will once again be off by one.

[romkatv]

I'm assuming the workaround has worked for you. Please reopen the issue if not.

Thank you! This resolves the problem.
