HunterPie Native cannot display Chinese

[hardcoreMG]

When I developed my plug-in for HunterPie, I used HunterPie Native. When tested, it worked very well. But when I send Chinese, it shows blank. The encoding used is UTF-8. How to solve this problem correctly.

By the way, where can I get Native documentation? For example, the color of the title, or the content of the icon, as follows:

Titile \n content

Thank you very much.

The code like this：
<STYL MOJI_LIGHTBLUE_DEFAULT><ICON SLG_NEWS> Titile </STYL> \n content
