Chinese normally [do not have spaces] and [wrapped char by char]. Current space wrap cleaves the sentence causing bad display when there are format spaces like the one between chinese and numbers and latin letters, between text and reference.
The following image shows a sentence cutted on " T ".

An ideal display will be like this (without space wrap):

(Chinese text: 按 T 打开科技面板开始新科技的研发。
Correspond english text in game: Press T to start a new research.
Direct translation: Press T to open science technology panel to start new science technologies' research and development.)
As I know, japanese have no spaces as well.
