Question

利基编程问题：我通过字节制作开发OpenType字体（而不是使用Fontlab或FontForge等设计工具），现在有一个自定义的OpenType-CFF字体，它实现了Basic Latin的一个子集unicode块（特别是它实现了.notdef和tilde）。

CFF块传递tx -3验证（http://www.adobe.com/devnet/opentype/afdko.html），整个字体通过TTX（https://github.com/behdad/fonttools）和Microsoft发送往返de / repompile ＃39; s＆＃34;字体验证器＆＃34; （http://www.microsoft.com/typography/FontValidator.mspx）不报告字体中的任何错误。将其作为自定义webfont加载（在支持otf的浏览器中作为普通otf加载，并在不包含浏览器的WOFF中包装）正确设置实现的字形样式。

然而，即使具有所有明显的正确性，Windows字体预览器也会报告它不是有效的字体文件，并且窗口不允许我安装它。我已经高低看了解Windows可以安装哪些窗口所需的信息，但互联网似乎充满了如何使用字体作为用户，而不是作为开发人员需要满足的要求。

我不太清楚包含这个问题的代码的最佳方法是什么，因为它不是传统的编程;生成器代码是用JavaScript编写的，但是该代码完全正常，并且生成一个用于所有意图和目的（保存一个）正确的字体。

如果您知道如何使用十六进制编辑器，则以下是字体的十六进制字符串：

如果有任何其他工具可用于确定字体是否已完成＆＃34;足以安装，或者如果有人知道文档解释字体在安装之前需要满足哪些标准，那么非常欢迎这些信息。当然，如果有人碰巧知道我的字体代码仍然缺失（无论是字节码还是TTX XML），或者他们看到奇怪/错误的位，我也对你的评论/答案非常感兴趣。

Answer 1

正如Typophile论坛上的某位人士指出的那样，就Windows而言，“名称”表格是不完整的。虽然Microsoft字体验证器没有标记任何问题，但字体必须列出以下名称表条目才能安装：

1: the regular font name
2: the font subfamily ("Regular", etc)
3: any (seriously, ANY) string to act as a unique font identifier
6: the postscript font name (a subset of true ASCII. Not ANSI)

我定义的字体使用的是NameIDs 1,2,4和5;虽然4和5实际上是“验证”所必需的，但它们与预览/安装完全无关，而3和6则至关重要。谁知道（严肃地说，谁知道......如果你这样做，我想在聊天或推特上与你交谈或者选择你的大脑=）

（请注意，仍需要4和5才能在OSX上安装字体）

2017年编辑：Microsoft的Font Validator于2015年开源，由于MS（由于法律原因）无法合并重要的社区贡献，因此设置了社区维护的分支，并且与https://github.com/HinTak/Font-Validator上的OpenType规范中的更改保持同步 - 如果字体验证器是您的工具集的一部分，那么绝对想要开始使用相反，这个叉子。

Answer 2

首先，我不知道AFDKO以外的要求。

我安装了DTL OTMaster Light，并报告created和modified值超出范围（customfont.otf）。它们位于Windows所需的head表中。

OpenType字体可以安装的窗口要求是什么？
