I'm using LyX 2.2.3, and I found that theorem names, such as theorem, case, remark, in Chinese are not shown correctly. For example, I have a .lyx file with content
> 定理 1. 一二三四五 > 案例 1. 六七八九十 > > > 備註 2. 十一時二十三 > in which 定理 is the Theorem environment, 案例 is the Case environment, and 備註 is the Remark environment. But after export to pdf (via pdflatex) it's shown as > åőŽçŘĘ 1. 一二三四五 > æąĹä¿Ń 1. 六七八九十 > åĆŹèĺż 2. 十一時二十三 > Only theorem names are garbled, but other Chinese words are normal. In Document settings, I've set CJK font to *bsmi*, language to *Chinese (traditional)*, and encoding to *Unicode (CJK) (utf8)*. The original LyX file is here <https://www.dropbox.com/s/ilvjvc6m380i55f/Abnormality%20of%20Chinese.lyx?dl=0> .
