Fish Shell Fix Emoji Spacing iTerm2 MacOS

Question

In iTerm2 using fish shell 2.7.1 emojis do not display properly

With Unicode 9 widths turned on in iTerm, emojis are wack

With Right Hand Prompt Without Right Hand Prompt

Without Unicode 9 widths, emojis are smushed.

How can I fix this?

Answer 1

This is due to an outdated wc-width function in fish for determining how much space each character gets. This supposedly will be fixed in fish 3. If you want emojis to work properly in fish 2.xx:

1. Build source from GitHub AND instead of cmake .. do cmake -DINCLUDED_WCWIDTH=OFF .. . This will use your system's wc-width function, which should be better when using MacOS.

2. Add set -g fish_emoji_width 2 to ~/.config/config.fish . This will make emojis by default have a width of 2, which should fix spacing issues.
