Sounds like a possible font issue with Simple Bible Reader, if there is a way to check the fonts in Simple Bible Reader you should do so to check and see if it as the correct font for Chinese. Esword uses a font called PMingLiU for both Traditional and Simplified Chinese.
The codes you have a problem with are HTML codes and will work fine if you have E-Sword 11 installed on your PC as it is designed to run html files
In fact, I use e-Sword®Version 11.0.6.
I don't know what's the problem.
