Fresh user account. Terminal.app and iTerm2 with UTF-8 set. Accented characters work fine in all applications ("å,ä,ö,é"). But some (wide?) unicode chars is not showing in some command line applications. I first discovered it in weechat, but in the bash shell it works fine.
In stock Mavericks bash:
DeoGloria:~ test$ echo -e "\xE2\x9A\x91"
⚑
Copying and pasting the flag char with mouse.
DeoGloria:~ test$ ⚑
-bash: ⚑: command not found
bash is working as expected. Starting default zsh, no config done
DeoGloria:~ test$ zsh
DeoGloria:~ test$ echo -e "\xE2\x9A\x91"
⚑
Showing alright. But not when I paste:
DeoGloria% <2691>
zsh: command not found: \u2691
Locale settings:
DeoGloria% locale
LANG="sv_SE.UTF-8"
LC_COLLATE="sv_SE.UTF-8"
LC_CTYPE="sv_SE.UTF-8"
LC_MESSAGES="sv_SE.UTF-8"
LC_MONETARY="sv_SE.UTF-8"
LC_NUMERIC="sv_SE.UTF-8"
LC_TIME="sv_SE.UTF-8"
LC_ALL=
Starting emacs or vi from zsh and pasting "⚑" works fine. It doesn't work in nano. I get an non-visual character.
I suspected some issues with ncurses, but bash, zsh, nano, emacs are all linked with
/usr/lib/libncurses.5.4.dylib (compatibility version 5.4.0, current version 5.4.0)
I'm out of ideas. Any pointers?

Interesting question! I did some tests on my side.
zsh
I did also several tests with other shells and results are not the same:
sh
bash
Ok, that should be the same as
sh
:csh/tcsh
Apparently, all that shells are not set with the same input/output options. I tried with xterm/terminal and iTerm2 to see if I could be a software dependant problem. That's the same everywhere.
I don't have the time to search/read that but you might find some useful informations about the zsh line editor here.
If you find it, keep me up-to-date, I would be pleased to have the final answer to your question.
