Subject: unicode in prompt breaks command search
Date: Thu, 16 Jan 2020 16:43:37 -0500 [thread overview]
Message-ID: <bac9b085-23b6-1e58-bc7d-715def0a22fe@acm.org> (raw)
For reasons, I put a multibyte unicode char in $PROMPT, this ends up
messing with zsh's idea of the current column, as it doesn't understand
the display width of $PROMPT.
For example reverse search, here's an example using <f0><9f><a1><85>
set PROMPT="🡅"
press C-r, see cursor gets indented another 3 spaces -- we're now at
column 5, which would be correct if each byte of $PROMPT was a separate
display char.
A slightly modified example is to enter some text before pressing C-r,
then the first 3 chars get retained on the display (but not the input
buffer at least).
Is this supposed to work?
This is ZSH 5.2 on a fedora 30 system, and an XFCE terminal. Let me
know if you need more info (I'm not on the list).
