我们使用 telerik 报告来生成 HTML 和 PDF 报告。这次对于容器版本，不知何故，在生成 PDF 报告时，telerik 抛出以下错误，
System.NotSupportedException: Font Century Gothic 9 Regular is not supported.

虽然我已经在容器上安装了世纪哥特式字体，并且还证明HTML 报告运行良好。只是PDF报告从telerik抛出字体错误。
我查看了 telerik 博客，但不明白为什么这会失败， 链接 https://docs.telerik.com/reporting/designing-reports-considerations-pdf https://www.telerik.com/forums/export-to-pdf-throwing-error
有趣的是，它适用于本地服务器，但不适用于容器，因此必须是 telerik 的 pdf 报告渲染所期望的一些安装或配置。请提出一些解决方法。
尽管存在奇怪的错误，但解决方案更奇怪，但有效。正如我在问题中所解释的那样，即使字体存在于容器下，并且经过几次搜索，我只找到了一个可能的答案，那就是将字体文件从"C：\Windows\Fonts"文件夹移动到其他地方，然后将其复制回同一文件夹。最终我尝试了这种方法，它奏效了。

不知何故，Windows操作系统有自己的方法来产生错误并解决相同的:)
