Container indicator, ⬢, not rendered properly on macOS

[michel-slm]

Bug Report

Current Behavior

When SSH-ing to a Linux host and then entering a Podman container (set up using Distrobox), the prompt is set to display info about the container by default (e.g. distribution and release version). This is displayed incorrectly on macOS (both in Terminal and iTerm2, even when using a Nerd Font) but works just fine on Linux

e.g.

michel in ~ 
⬢ [fedora:39] ❯ 

michel in ~ 
⬢ [debian:stable] ❯ 

On macOS the ⬢ is not shown at all, and after typing a few characters and erasing them with backspace, the first letter is still rendered

Expected Behavior

Additional context/Screenshots

Missing ⬢ and further rendering issues (no rendering issue if the prompt does not contain ⬢, e.g. outside a container)

Same commands, on Linux

Possible Solution

Environment

• Starship version: 1.18.2
• Shell type: fish
• Shell version: 3.7.0
• Shell plugin manager: fisher
• Terminal emulator: iTerm, Terminal
• Operating system: macOS 14.3 to 14.4.1

Relevant Shell Configuration

if status is-interactive
    # Commands to run in interactive sessions can go here

    # vi mode
    fish_vi_key_bindings
    # https://fishshell.com/docs/current/interactive.html#vi-mode-commands
    function fish_user_key_bindings
        # Execute this once per mode that emacs bindings should be used in
        fish_default_key_bindings -M insert

        # Then execute the vi-bindings so they take precedence when there's a conflict.
        # Without --no-erase fish_vi_key_bindings will default to
        # resetting all bindings.
        # The argument specifies the initial mode (insert, "default" or visual).
        fish_vi_key_bindings --no-erase insert
    end

    # handle cases (e.g. macOS) where we can't set the default shell
    if not string match "*/fish" $SHELL >/dev/null

Have you tried using a different symbol for the container module?
Does it only happen with this symbol or generally with the container module?
