No, they are single display width. Your russion character works fine
for me too, only crashes with the characters i listed.

This should create the files i have,

mkdir /tmp/foo
cd /tmp/foo
a=`echo +ANg- | iconv -f utf-7 -t utf-8`
touch ${a}a ${a}b
zsh -f
autoload -U compinit; compinit
ls <tab><tab>

That is all i have to do to get the crash. (I didn't compile with
--enable-zsh-debug, because then i only get an error message like
"BUG: substring ends in the middle of a metachar in ztrsub()", instead
i specified the flags manually)
