[问题]中英文斜体的倾斜程度不一致

[FFFrog]

我在language-selector.conf中配置了sans-serif、serif和monospace的字体替换。现在的效果基本上满意了，但有个奇怪的地方：中文斜体的倾斜程度比英文斜体要大得多，如我截图中所示。

而若是使用单独的中文字体，如华文中宋、微软雅黑的时候，斜体的倾斜程度却又没有这么大，很自然。

有没有办法通过配置language-selector.conf文件，单独调整sans-serif、serif和monospace里面中、英文斜体的倾斜程度呢？


附我的language-selector.conf文件内容：

大哥啊，那是系统为了表示正在播放的歌曲特别加斜的。

[FFFrog]

我当然知道那是斜体了。你没看清楚我的意思。

我是说，这种用中英文字体混合而成的系统字体（sans serif、serif、monospace）中，在显示斜体时，中文比英文更斜，看起来不一致。
而单独用其中的中文字体（不选择sans serif而直接选择微软雅黑）时，它的斜体却又没有这么斜了。
