Right-arrow character and autocomplete

Right-arrow character and autocomplete

[Darío Cuevas]

Greetings,
perhaps this has been reported before (many times?), but here it goes.
If there is an arrow character in the prompt, hitting TAB to
autocomplete will always duplicate the command written so far.

I've had this problem for a couple months already (presumably after an
zsh update), on both kubuntu 20.04 and manjaro(KDE). To reproduce, one
needs only do PROMPT="→" on .zshrc, open a terminal, start typing some
command (e.g. ls) and hit TAB: the command (ls) will be written twice.
Happens every time.

If you need any more information, I'm happy to help.

Best,
Darío Cuevas

This usually happens when you put non-ascii characters in PROMPT (like that
arrow) but your locale is not UTF-8. Run `locale` to confirm. To fix this,
install and enable a UTF-8 locale.

This can also happen when TERM environment variable doesn't match the real
terminal type. To fix this you need to avoid overwriting the value of TERM
set by the terminal.

Although that's the best solution, if for some reason that can't be
done you can try using the "glitch" prompt escape to tell zsh what the
actual character width is.

PROMPT="%1{→%}"

tells zsh that although there are 3 bytes in the %{...%} sequence, it
should be treated as occupying only one character position.

Apologies, seems I forgot to reply to all. See my message below.

Tl:dr: my OS had indeed a locale problem which I now corrected. Now it all
works well. Thanks for your help and sorry for the false report.
