关于SDK的问题(Question about SDK's)

 问题似乎出现在/etc/fonts/conf.d/中的fontconfig规则中，而不是JavaFX中。 我还没有找到解决这个问题，但使用fc-match会产生相同的结果 
 
fc-match sans:regular:roman 
"LiberationMono-Regular.ttf": "Liberation Mono" "Regular"
 
 我在另一个论坛上发现了一个类似的问题： 字体问题，monospace用于serif和sans-serif系列 ，但没有解决方案。 
 
 添加字体配置文件，例如/etc/fonts/conf.d/88-liberation-hack.conf将解决问题 
 
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>

<alias>
  <family>sans-serif</family>
  <prefer><family>Liberation Sans</family></prefer>
</alias>

<alias>
  <family>serif</family>
  <prefer><family>Liberation Serif</family></prefer>
</alias>


<alias>
  <family>monospace</family>
  <prefer><family>Liberation Mono</family></prefer>
</alias>

</fontconfig>

The problem appears to be in the fontconfig rules in /etc/fonts/conf.d/, not JavaFX. I've not yet been able to figure out to fix this, but using fc-match produces the same results
 
fc-match sans:regular:roman 
"LiberationMono-Regular.ttf": "Liberation Mono" "Regular"
 
I found a similar problem on another forum: Font issue, monospace used for serif and sans-serif families, but without a solution.
 
Adding a font config file, e.g. /etc/fonts/conf.d/88-liberation-hack.conf will fix the issue
 
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>

<alias>
  <family>sans-serif</family>
  <prefer><family>Liberation Sans</family></prefer>
</alias>

<alias>
  <family>serif</family>
  <prefer><family>Liberation Serif</family></prefer>
</alias>


<alias>
  <family>monospace</family>
  <prefer><family>Liberation Mono</family></prefer>
</alias>

</fontconfig>
