加载所有这些必要的吗？我的网站只迎合说英语的用户，因此我宁愿不为拉丁语或西里尔语的用户加载内容并提高性能。删除它们是否安全？另外，如果我删除那些我保留的那些，因为在上面的示例中，我不会看到任何只是简单的英语？

Answer 1

如果您不使用西里尔文，则可以安全删除相应的@font-face规则。

但保持它并不会有任何损害：如果您的内容中没有任何西里尔字符，浏览器将不会下载西里尔字体。只有在@font-face规则中指定的Unicode范围内有字符时才会下载它，在这种情况下：

unicode-range: U+0400-045F, U+0490-0491, U+04B0-04B1, U+2116;

谷歌网页字体为其他语言加载了大量额外的CSS，删除它们是否安全？
