Right-to-left text rendering can be triggered in the UI by user supplied input

[dwt]

Summary

My git username contains a unicode line direction change character, to check how software handles this.

Zed does not, it leads to this hilarious result:

Steps to trigger the problem:

1. Set your username to something like this in the git config

   [user]
    name = ‮rekcäH nitraM‮
   

2. Enjoy the breakage everywhere

Actual Behavior:

Expected Behavior:

22 hours ago should not be inverted, as the altered state from the username has leaked into the user interface of zed.

:D fun one. We don't even support editing files containing RTL characters right now, so probably won't get to this soon...

How do UIs typically work around this? I guess by using separate calls to the font rendering engine for each field.

@ConradIrwin That sounds about right. One could also try to filter, but that seems like a dark ally one does not want to venture in.
