OSX Terminal Fix - perl: warning: Setting locale failed.

gistfile1.txt

When running certain commands like ssh or git within Terminal on OSX you may get notices like the one below, which can be annoying.
      
      perl: warning: Setting locale failed.
      perl: warning: Please check that your locale settings:
          LANGUAGE = (unset),
          LC_ALL = (unset),
          LANG = "en_US.UTF-8"
      are supported and installed on your system.
      perl: warning: Falling back to the standard locale ("C").
      
The fix is simple:

Adding the following lines to ~/.bash_profile on my your local machine, the warning should go away:

export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8

Hope this helps someone rid themselves of annoyances.

My quick way to disable that message: Open Terminal -> Preferences -> Advanced tab -> uncheck to Set locale environment variables on startup

Nice tip. Thanks.

On macOS Catalina (10.15.4) using iTerm2, I made this work by export LC_ALL=en_US.UTF-8 only.

Thanks @sshine

On macOS Sonoma (14.1) using iTerm2 , zsh , I made this work by appending export LC_ALL=en_US.UTF-8 only in ~/.zshrc .

On iTerm:
Settings... > Profiles > Terminal > Uncheck Set locale variables automatically

you rock , this made my day
