Hi,
I am trying to use the new insert-unicode-char in a vi emulation - insetmode,
using
autoload insert-unicode-char
zle -N insert-unicode-char
bindkey -v '^y' insert-unicode-char
It works, accept I cannot enter two unicode characters in a row. After I have
finished entering the first one by entering its closing ^Y, the opening ^Y of
the second character just beeps. I can start another insert-unicode-char
sequence only after typing at least one more character (of course, a
"solution" is to hit any character and to follow it by a backspace ;-)).
I am using the up-to-date zsh-4.3.0-dev-1 (ChangeLog revision 1.2939,
insert-unicode-char revision 1.3) on a RedHat 9 and system.
Best,
Zvi.

I now checked this also on our solaris systems. The situation is that both
insert-composed-char and insert-unicode-char fail, on the line which tries to
print a unicode esacep sequence. However, on these machines, I get
'zsh: cannot do charset conversion' on such print commands (e.g., print
\\u21 , which should print a bang!), a message which is generated by
Src/utils.c. I am using a LC_CTYPE=en_US.UTF-8 locale, and zsh in configured
with --enable-multibyte (which is a mistary by itself, since on my RedHat
system, this flag is not needed since configure figures it out by itself).

Yes, that was an oversight. It needs an extra flag to check that it's
really on the second stage rather than the first, otherwise it gets
confused by back-to-back uses.

Another remark: In the solaris 9 system, I have two copies of libiconv
installed: one in /usr/lib (the solaris native), and one in /usr/local/lib
(from GNU libiconv-1.10), and the latter directory is in the LD_LIBRARY_PATH
both in installation time and in run time, and ldd =zsh shows that it uses
/usr/local/lib/libiconv.so.2. On the Redhat system, where unicode esacpe
sequences work, I am using glibc.

It's quite possible that the multiple libiconvs are significant, since it
works OK on Solaris 8 here. The error message and the configuration
suggest this call is failing:
cd = iconv_open(nl_langinfo(CODESET), "UCS-4BE");
although it's possible it's not using the iconv code at all for
some reason, which would happen if neither HAVE_ICONV nor any of
the alternative conversion types were available. The dependence
on the shared library might conceivably be indirect.
We don't have a Solaris 9 for trying out multibyte mode on, but I know that
Solaris 8 doesn't set __STDC_ISO_10646__, which we're using to detect
the capabilities automatically---it saves a lot of configuration
probing. It sounds like it probably isn't set in your case, otherwise
the shell would use wctomb() rather than iconv, avoiding the other problem.
With enough automated tests for things like the effect of wctomb() we
could probably avoid all this, but that's hard work.
