Answer 1

这个问题实际上来自试图创建pdf的itext库。

1. 检查您是否有正确的拼写字体名称(案例感觉)。
2. 可能您的字体不受支持(见下文)，尝试使用其他字体或其他格式的相同字体。

为什么不支持@参见Bruno on I-text问题：

Adobe最初是一家销售字体的公司: PostScript字体(类型1)。苹果和MicroSoft开发了一种相互竞争的字体格式: TrueType (ttf)。不幸的是，苹果的标准和MicroSoft的标准相去甚远。字体与平台有关。Macintosh的字体不一定适用于Windows，反之亦然。然后MicroSoft和Adobe提出了一种新的独立于平台的字体格式: OpenType。有两种风格:带有PS轮廓的OpenType (otf文件)和带有TrueType大纲的OpenType (ttf或otf文件)。

因此，人们总是猜测你的ttf是Macintosh的TrueType字体，而不是带有TrueType轮廓的OpenType字体。
