Tips: solve the double/random characters when ssh to remote macOS/Ubuntu

When I start to use Ghostty on serveral my servers, found there are some double characters while type remote host with zsh shell.

The simply resolution to append on your shell configuration file.

export TERM=xterm-256color

Here is what I did

JimmyMBA.local ➜  ~  ssh -l jimmy.liao localhost
Last login: Fri Jan 17 13:09:39 2025
JimmyMBA.local ➜  ~  cclearcc   ccccccccaabbccdde
JimmyMBA.local ➜  ~  eexitexexxiexiitexit
Connection to localhost closed.

JimmyMBA.local ➜  ~  echo "export TERM=xterm-256color" >> ~/.zshrc
JimmyMBA.local ➜  ~  . ~/.zshrc

JimmyMBA.local ➜  ~  ssh -l jimmy.liao localhost

JimmyMBA.local ➜  ~  clear

Thanks.
