thank you for your question.
Currenly, the "setString" is properly called when setting the language and it then seems the zh_CN was properly deployed.
Nevertheless, your zh_CN.conf file is normally defined as follows:
Bundle-Version: 1.0 Bundle-Name: zh_CN Configuration-Script: AddResDir ../resources/ Name: text Type: Text Configuration-Script: AddResource zh_CN/zh_CN-ak-cur.res AddResource zh_CN/zh_CN-lk-text.res AddResource mul/mul-lk-english_secondary_2.res SetHalfWidthFullWidthScheme AUTO EnableAlienCharacters SetTextListSize 1 SetWordListSize 5 SetCharListSize 1
In your case, I do not see the "mul" directory and the corresponding mul-lk-english_secondary_2.res resource. These are normally located into the myscript-iink-recognition-text-zh_CN.zip file you downloaded. Please ensure to properly create the "mul" directory and add the corresponding resource.
