英文:
"Windows Forms" seems to support OTF-Fonts. But why does it work, when everyone else says the opposite?
问题
我曾以为“Windows Forms”不支持OTF字体。但尝试后，我发现情况相反。
- 我刚刚创建了一个使用“.NET Framework 4.8”和C#（后来我也在VB.NET中尝试了相同的操作）的新“Windows Forms”项目。
- 我在一个全新的窗体中设置了一个标签和一个按钮。
- 我在按钮的单击事件中打开了一个“System.Windows.Forms.FontDialog”类的实例，并通过选择的字体设置了标签的字体。
然后我启动了应用程序，点击按钮，选择了我安装的OTF字体，并查看了结果。
对我来说，它完美地工作，但为什么每个人都说“Windows Forms”不支持OTF字体呢？
我还尝试了不同的OTF字体，并多次检查它们是否确实是OTF字体，它仍然能够正常工作。
我还在全新的虚拟机上尝试了这个“Windows Forms”应用程序和OTF字体。它仍然可以正常工作。
有人知道我可能做了什么与其他人不同的事情吗？
我提出这个问题的原因是，我认识的某人在选择OTF字体后，一个“Windows Forms”应用程序崩溃，并显示只支持TTF字体的异常消息。但在我的环境中，我无法重现这个问题，并且可以在“Windows Forms”应用程序中使用OTF字体而没有任何问题，但我不知道为什么。
英文:
I thought that "Windows Forms" doesn't support OTF-Fonts. But by trying it anyways I realized the opposite.
- I just created a new "Windows Forms" project, which uses the ".NET Framework 4.8" and C# (later I made the same in VB.NET).
- I set a label and a button in a brand new form.
- I made the click event of the button open an instance of the class "System.Windows.Forms.FontDialog" and set the font of the label by the chosen font.
Then I started the application, clicked on the button, chose my installed OTF-Font and looked on the result.
For me it works perfectly well, but why, when everyone says that OTF-Fonts are not supported in "Windows Forms"?
I also tried different OTF-Fonts and also checked multiple times if they’re actually OTF-Fonts and it still works.
And I also tried this "Windows Forms"-Application and the OTF-Fonts on a brand new virtual machine. It still works.
Has anyone an idea, what I’ve perhaps have done different than everyone else?
The reason I asked this question is that someone I know has the problem that a "Windows Forms"-Application crashes with the exception message, that only TTF-Fonts are supported, every time an OTF-Font was chosen. And I'm unable to reproduce this issue in my environment and can use OTF-Fonts in an "Windows Forms"-Application without any problems, but don't know, why.

这个问题可以通过在程序运行时安装字体，然后再尝试使用它来复现。
出现了OTF格式有问题的消息（只有TTF格式会被接受），但真正的原因是字体的安装或安装方式。
安装TTF字体时也会出现相同的错误消息。
因此，当字体安装出现问题时，会引发异常，出现的错误消息会误导。
英文:
This problem can be reproduced by installing a Font in runtime of the program before he tried to use it.
The message that the OTF-Format was to blame (only the TTF-Format will be accepted) occured but the true reason was the installation or the way how the font was installed.
The same with the installation of the TTF-Fonts (with the same error message).
So when something with the installation of the Font went wrong the exception happens and the occurring error message is misleading.
