外部 CSS 编码问题？

Question

我的外部 CSS 文件直到今天都运行良好。下面的图片是使用 chrome 查看源代码的样子。我必须注意，我在 css 文件的顶部使用字符集 utf-8。 @charset "utf-8";我也试过了Content-Type: text/css; charset=UTF-8

此外，我正在使用 cloudflares 免费 CDN，并且在使用他们的名称服务器时遇到了一些小问题，但我大约一周前开始使用他们的服务并且直到今天才遇到 css 的问题。

有人有想法吗？

编辑：我在我的 htcaccess

中使用了以下内容

    # compress text, html, javascript, css, xml:
    AddOutputFilterByType DEFLATE text/plain
    AddOutputFilterByType DEFLATE text/html
    AddOutputFilterByType DEFLATE text/xml

根据上面的评论，尝试以下代码段。

自动 UTF-8 编码

# Use UTF-8 encoding for anything served text/plain or text/html
AddDefaultCharset utf-8

# Force UTF-8 for a number of file formats
AddCharset utf-8 .atom .css .js .json .rss .vtt .xml

压缩文本文件

<IfModule mod_deflate.c>

    # Force compression for mangled headers.
    # http://developer.yahoo.com/blogs/ydn/posts/2010/12/pushing-beyond-gzipping
    <IfModule mod_setenvif.c>
      <IfModule mod_headers.c>
          SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)\s*,?\s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding
          RequestHeader append Accept-Encoding "gzip,deflate" env=HAVE_Accept-Encoding
      </IfModule>
    </IfModule>

    # Compress all output labeled with one of the following MIME-types
    # (for Apache versions below 2.3.7, you don't need to enable `mod_filter`
    #  and can remove the `<IfModule mod_filter.c>` and `</IfModule>` lines
    #  as `AddOutputFilterByType` is still in the core directives).
    <IfModule mod_filter.c>
      AddOutputFilterByType DEFLATE application/atom+xml \
                                    application/javascript \
                                    application/json \
                                    application/rss+xml \
                                    application/vnd.ms-fontobject \
