配置文件：/etc/fonts/conf.d/64-language-selector-cjk-prefer.conf

該文件配置了 Noto Sans CJK 的優(yōu)先級。默認內(nèi)容如下：

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <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>
</fontconfig>

可以看到，JP 優(yōu)先于 SC。直接將 JP 移至最后即可。修改后的配置文件：

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <alias>
        <family>sans-serif</family>
        <prefer>
            <family>Noto Sans CJK SC</family>
            <family>Noto Sans CJK TC</family>
            <family>Noto Sans CJK JP</family>
        </prefer>
    </alias>
    <alias>
        <family>monospace</family>
        <prefer>
            <family>Noto Sans Mono CJK SC</family>
            <family>Noto Sans Mono CJK TC</family>
            <family>Noto Sans Mono CJK JP</family>
        </prefer>
    </alias>
</fontconfig>

修改完成后注銷重新登陸生效
