Entering zero-width chars in the ^r prompt messes up display

Entering zero-width chars in the ^r prompt messes up display

[Mikael Magnusson]

I pasted a filename from a webpage and it had some <200b> in it, so i
did ctrl-r ctrl-shift-200b to delete them quickly, but instead ended
up with weirdness. The same thing happens for combining chars like
<305>. Also notable is that the search seems to fail, while it works
fine for other utf-8 chars, including double-width japanese chars.

I was unable to reproduce this but did not find anything explicit about
this being fixed, etiher.

Could you check again with current cvs? If it's still open, I will add it
to the bug tracker.

This still happens to me both with -f and without, it happens on 4.3.4
too (didn't try any other versions). If it wasn't clear, the
ctrl-shift-200b part is terminal specific, if you don't use urxvt you
would need to input it some other way (for example echo
$'\u200b'|xclip and then just middle click after pressing ctrl-r).

Ah, thanks. Although I defaut to UTF-8, I don't use anything
other than what en_us and de_de give me.

In any case, I can reproduce this on cvs1228 with zsh -f.

I will let this sit here until next year and then file it ;)
