Paste with Ctrl removes leading special character in SSH

[fbienz]

Windows Terminal version

1.20.11271.0

Windows build number

10.0.22631.0

Other Software

openssh-client/jammy-security,now 1:8.9p1-3ubuntu0.6

Steps to reproduce

Connect to remote Linux server via SSH using WSL or Powershell.
Paste a string starting with one of these characters []{} using Ctrl+Shift+v, Ctrl+v or Ctrl+ Right Click.
Example: [rlkdjf[]{}dt

Expected Behavior

Complete String gets pasted into the Shell.

Actual Behavior

Leading character and the second character are removed from the String.

Using Shift+Insert or Right Click does not remove the leading characters.

This has worked until the latest update (winget package). I'm assuming this is form the 1.20 update.

Thanks for the report! I'm sorry that we haven't been able to reproduce this yet. I just gave it a try with 1.22 (Canary) in zsh and bash over ssh, one of which supports bracketed paste mode and the other of which does not.

Would you be able to test this out in the Canary channel/?

Hi,

I tested it again using following version:
Terminal (Portable)
Version: 1.22.240822001-llm

The Problem stays the same.

I have learned a few things though:

• zsh does not have this issue in either version. (although i could only test it by launching zsh through bash)
• The behavior is different for Debian 10 vs Debian 12 remote host

In case the remote host is Debian 12, pasting works without the brackets being removed, except when pasting a password in the password mask.
In that case only right Shift+Insert and Right Click paste correctly.

Since there were some updates, this is the current version I'm using: 1.20.11781.0

Does this repro if you use ssh within WSL /?
