I am using curl on my Macos Catalina terminal app, and the text I enter in stdin gets altered on me pressing enter Enter. For a simple example:

curl -d " 印度是最好的 The weather is good" -X POST http://localhost:8000/questions/21/
curl: (1) Protocol "hhttp" not supported or disabled in libcurl

is actually entered as :

 curl -d " 印度是最好的 The weather is good" -X POST hhttp://localhost:8000/questions/21/

, which I can see from previous command on terminal Control + P.

P.S - I've entered the command and thus, it shows libcurl error.

For an english sentence - you can see the error below:

terminal error

I have no idea why this is happening, I'm using zsh shell and ohmyzsh along with it - and this is happening the first time to me.

Adding an image here too, for further investigation.

terminal typing problems

My .zshrc configuration is here

  • Probably a bug in terminal. I tried copy-pasting the line you posted into Terminal.app on macOS Big Sur and it does not work at all. It basically breaks from the first Chinese character onwards.

  • @MarlonRichert - Actually, it isn't a problem with chinese text, it happens to me for regular english text too!

    Turn off OhMyZsh (and leave it off, it's a cancer). Does the problem still occur?

  • There isn't enough information to help you here. It's difficult to diagnose this without trying things out. To get help, you need to figure out a way other people can reproduce the problem. The first step is to see if you can reproduce in another terminal window. Then, see if you can reproduce without your .zshrc; if you can't, you'll need to post your complete .zshrc and all the files it loads. If you can reproduce it without Chinese text, it would help.

  • Does it matter whether you typed the command or copy-pasted? Can you reproduce this with commands other than curl? If you press Up to edit the command line, does the extra h appear? If you run fc to edit the last command in an external editor, does the extra h appear? Is the problem always with the letter h or sometimes with other letters? Does the problem occur with every h or only some? Does the problem occur with other terminals such as iTerm?

I don't have any problem with trying to paste that line into zsh running in Terminal.app. Some testing...

zsh: processed normally
dash: processed normally
oksh: processed normally
pdksh: processed normally
tcsh: processed normally
bash: processed normally
fish: processed normally
ksh: takes the Chinese as editor commands and weirds out

I'll report that as a ksh bug, I suppose.

But your problem would seem to be OhMyZsh, not Terminal.app. I can replicate the ksh behavior in iTerm as well.

Edit: ksh has a bug with multibyte characters and the KEYBD trap. See https://github.com/ksh93/ksh/issues/307 and https://github.com/att/ast/issues/197
