Add option --with-unicode9 on devel and head for Unicode 9 character width support. The option is not enabled by default because support is required from both the shell and the terminal emulator; disparity could cause garbled output. A simple test case is "echo 👍1👍2👍3" at the prompt: - If neither zsh nor the terminal emulator has Unicode 9 width tables, each digit will overlap with its previous emoji, but editing will still be very much possible; - If zsh has Unicode 9 width tables but the terminal emulator doesn't, the string will be garbled and editing will be very difficult; - If both zsh and the terminal emulator have Unicode 9 width tables, output will be correct and editing won't be hindered. Terminal.app currently doesn't support Unicode 9, making the option a tough sell as default. For the record, iTerm2 nightlies since 08/08/2016 have opt-in Unicode 9 width support and version switching. See https://gitlab.com/gnachman/iterm2/wikis/unicodeversionswitching.
