ZSH: prompt line not wrapping correctly

See original GitHub issue

Details

OS version: MacOS Catalina

Steps to reproduce

Run the demo, it starts with a bash
type a lot of text, note that the prompt line wraps correctly, deleting characters works as expected
Press CTRL+C, start zsh
type a lot of text, note that the prompt line does not wrap, deleting characters will eventually erase the wrong line

This doesn’t happen in Terminal.app or iTerm. It also does not happen in VSCode 1.39.2

I tried xterm@3.0.0 demo and it also shows this wrong behaviour.

Turns out this seems to be somewhat Mac specific. The LC_CTYPE environment variable was not set, which will mess up encoding. Manually setting it to “en_US.UTF-8” or “UTF-8” fixes the problem. VSCode and Terminus both have special handling for this kind of problem:

I’m closing this as it’s not xterm.js related.

@jerch Coming from this problem, your description above (and also what’s in the new encoding guide) exactly replicates what I’ve seen! Thanks for the explanation, it all makes sense now!
