Can typora support Chinese fonts or 'otf' fonts?

[rliangcn]

Hi, I followed the instruction in typora support for customizing font in css.
It seems not work for me.

step 1.

I opened the themes folder, and created 'base.user.css' file, the contents in it is as follows:

/* latin */
@font-face {
    font-family: 'SourceHan';
    font-style: normal;
    font-weight: 400;
    src: local('SourceHan'), local('SourceHan-Medium'), url('./fonts/SourceHanSerifSC-Medium.otf') format('otf');
  }
  
  /* latin */
  @font-face {
    font-family: 'SourceHan';
    font-style: normal;
    font-weight: 700;
    src: local('SourceHan Bold'), local('SourceHan-Bold'), url('./fonts/SourceHanSerifSC-Bold.otf') format('otf');
  }
  
  body {
    font-family: 'SourceHan', sans-serif;
  }

step 2.

I created the 'fonts' folder inside 'themes' and copied the SourceHanSerifSC-Medium.otf file for debugging.

result

I saved the css file, restart typora, but the Chinese font seems not changed.

Am I wrong in some steps? or can typora support these sorts of fonts? Thanks
