Double byte issue in non english windows

I m using simplifed chinese installed working well but when i copy words in winword of simplified chinese windows and then paste in spark,

the words especially the special characters will become double byte as shown on pic. But wndows to windows client no the problem.

Only mx lanugaes of windows / pure chinese windows … ANY idea can fix it to single byte ?

Using Spark? How it works with the latest 2.7.0 build? http://bamboo.igniterealtime.org/artifact/SPARK-INSTALL4J/shared/build-665/Insta ll4j/spark_2_7_0_665.exe
