I'm not immediately able to reproduce this (with zsh 5.0.8 or 5.2). Can you reproduce this problem with no other plugins/configuration loaded?

% zsh -f
%% source zsh-autosuggestions.zsh
%% echo 为美好的世界献上祝福
%% e

Going to go ahead and close because I can't reproduce with the info given. Will reopen if/when I get more info.
