“门” looks weird on my system default font

On my system, the “门” character looks super weird. I expect it to look like this:

But instead it looks like this:

I'm running Xubuntu 16.10 with the Chinese Language pack but not the Japanese language pack installed. I don't know what font it's displayed in but the second screenshot is from my system default.

Solution 1:

You can use fc-list :lang=zh-cn to list all fonts you install. I believe it is the bug in Ubuntu. Your system may use the wrong font to show simplified Chinese.

Take a look at your /etc/fonts/conf.d/64-language-selector-prefer.conf file, you may find the following:

<alias>
      <family>sans-serif</family>
      <prefer>
         <family>Noto Sans CJK JP</family>
         <family>Noto Sans CJK SC</family>
         <family>Noto Sans CJK TC</family>
      </prefer>
   </alias>
   <alias>
      <family>monospace</family>
      <prefer>
         <family>Noto Sans Mono CJK JP</family>
         <family>Noto Sans Mono CJK SC</family>
         <family>Noto Sans Mono CJK TC</family>
      </prefer>
   </alias>

What you need to do is move JP item to last. Highly recommand you to install Google Noto.
