Multibyte Input On OS X Again...

Multibyte Input On OS X Again...

Hello,

I have emailed the list before about the problems I have with  
multibyte input using zsh on OS X.  I still can't get it to work, I  
think that it has to do with composited versus non-composited  
characters possibly, when I have to composite a character (hit one key  
then another) to get a specific character but that character is a  
single character on the command line things go badly.  In bash with  
readline everything works fine.  I made a movie of the problem in zsh  
and then showing bash doing just fine.  Hopefully it will help.  The  
character sequence that you can partially see being pressed in the  
keyboard viewer is "opt-6" then "i".  In my keyboard layout this gets  
i with a hat.  Anyway, hopefully this movie is also watchable in  
linux, etc.  It should be a fairly standard quicktime container with a  
short H.264 movie inside, no audio.

Thanks,
Jordan Breeding

But note that there are other cases where zsh does fine while bash
doesn't behave correctly, e.g.

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=397086

zsh (after an "unsetopt PROMPT_CR") does fine. This case concerns the
output of a combining character, but I think that the input and output
are related. So, please, don't add a bug here when fixing the problem. :)

Another problem specific to bash:

vinc17@prunille:~/blah$ mkdir é
vinc17@prunille:~/blah$ echo [TAB]

gives:

vinc17@prunille:~/blah$ echo é/

If you type the right arrow several times, the cursor moves backward
and forward alternatively.

Hmm, at least with Bash 3.2 on OS X I don't seem to have the problems  
that you have with bash.  Anyway, I just hope that eventually  
multibyte input/output in zsh will improve, because other than  
multibyte support that works the way I would like it to zsh has just  
about everything I could possibly ask for.
