This is a simple HTML page with both LGC and CJK characters:
<html>
<head>
<meta charset="UTF-8"/>
</head>
<body>
<pre style="font-family: serif;">
aaaa
ββββ
ДДДД
いいいい
일일일일
大大大大
</pre>
</body>
</html>
What is expected: All characters are displayed in serif. This is the case in Firefox.
What has happened: Chromium only displays LGC chars in serif, but CJK chars in sans-serif.
My Chromium font settings have standard=sans, serif=serif, sans=sans, mono=mono.
I'm on Linux and my fontconfig alias of serif is:
<alias>
<family>serif</family>
<prefer>
<family>Droid Serif</family>
<family>Noto Serif CJK JP</family>
</prefer>
</alias>
And fc-match -s serif confirms these as top results.
If I change the style in HTML file, replacing serif by Droid Serif,Noto Serif CJK JP, then it works. But I couldn't figure out why Chromium doesn't work with fontconfig in this way. It seems like a kind of fallback issue.
