Hello, I have just found than having this character on command line:
$'\xf0\x9f\x8d\xbe' (that would be a 🍾)
makes the cursor unable to advance when inserting characters (it seems that
each character is overwriting the previously entered one, but when checking
the history the characters where alla added correctly, although in the
wrong position)
Hope that was clear enough, maybe this is already fixed in 5.8.1 or 5.9?
thanks

I'm unable to reproduce this in either 5.8 or 5.9.  Is it possibly
specific to a terminal emulator or locale setting?

Hello Bart, I normally use terminator as my terminal emulator. I have tried
launching xterm and the result is the same.
I use zsh 5.8 (x86_64-pc-linux-musl) (the hermetic version provided by
Roman: https://github.com/romkatv/zsh-bin)
which seems to be the culprit, since if I switch to the zsh 5.1.1 provided
by the os of the vm where I am testing the problem does not manifests.
By the way the problem happens only when the cursor is placed before the
4-bytes character.
regards

Ahh.  I wonder if this is a side-effect of musl's "special" C locale
(see workers/50235):

Still not reproducible on Ubuntu 20.

Just tried an ubuntu 18.04 with zsh 5.4.2 (x86_64-ubuntu-linux-gnu)
and I am able to reproduce.
I tried also with gnome-terminal, same result.
I have tried en_US.utf8 and it_IT.utf8, can you share yours?
thanks

sorry, should have been:

For the locale I have tried en_US.utf8 and it_IT.utf8, can you share yours?

At least that rules out musl libc.

I'm using LANG=en_US.utf8 ... I don't have Italian locales installed.
I have not tried changing the locale variables other than LANG, should
I?  Or perhaps you need to provide more specific instructions.

I've tried Gnome terminal and xterm.  xterm is not able to display the
glyph at all (I just get a 2-position-wide box) but I am able to move
the cursor back and forth past it and insert single-byte characters
anywhere around it.

This is with the stock Ubuntu zsh 5.8 and with 5.9 built from git
clone.  I've also tried inserting the character into the line editor
both with copy-paste from your original email and with `print -z
$'\xf0\x9f\x8d\xbe'`

Can you try running `cat`, pasting 🍾 and then typing something after
it? Does this also cause cursor issues for you?

Roman.

P.S.

I cannot reproduce the issue you've described on Ubuntu 21.10 with zsh
5.8, LC_ALL=C.UTF-8 and xterm or gnome-terminal.

Hi Roman, just to clarify, the problem happens only when the cursor appears
before the character.
I tried your suggestion and there were no issues

Bart: this is the output of locale:
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC=it_IT.UTF-8
LC_TIME=it_IT.UTF-8
LC_COLLATE="en_US.UTF-8"
LC_MONETARY=it_IT.UTF-8
LC_MESSAGES="en_US.UTF-8"
LC_PAPER=it_IT.UTF-8
LC_NAME=it_IT.UTF-8
LC_ADDRESS=it_IT.UTF-8
LC_TELEPHONE=it_IT.UTF-8
LC_MEASUREMENT=it_IT.UTF-8
LC_IDENTIFICATION=it_IT.UTF-8
LC_ALL=

I tried with
LC_ALL=C.UTF-8 zsh
locale
sed: -e expression #1, char 18: Invalid collation character
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="C.UTF-8"
LC_NUMERIC="C.UTF-8"
LC_TIME="C.UTF-8"
LC_COLLATE="C.UTF-8"
LC_MONETARY="C.UTF-8"
LC_MESSAGES="C.UTF-8"
LC_PAPER="C.UTF-8"
LC_NAME="C.UTF-8"
LC_ADDRESS="C.UTF-8"
LC_TELEPHONE="C.UTF-8"
LC_MEASUREMENT="C.UTF-8"
LC_IDENTIFICATION="C.UTF-8"
LC_ALL=C.UTF-8

the problem still appears

Have you tried it in any program other than zsh that also allows you
to move the cursor?

Hey Roman, are we going to have a pre-build of the latest?  I'm 
helplessly lazy now :-)

You mean https://github.com/romkatv/zsh-bin, right? I'll build it
eventually but there is no ETA. Sorry! There are no changes in 5.9
that affect me personally, so updating zsh-bin goes into my altruistic
TODO list, which is rather long.

Roman.
