我有一种字体，具有一些光学尺寸，我想使用它。我尝试了两种解决方案（如下），但没有成功。如何使用本地字体的光学尺寸？我尝试的解决方案：
使用
\definefontfamily，它给了我正确的基本替代方案（斜体，粗体等）并正确转换---为破折号，但不支持根据大小更改字体（正如我从文档中理解的那样）。使用 typescript，它没有给我正确的替代方案（更多内容见下文）也没有转换
---为长破折号。我无法理解如何以这种方式配置光学尺寸（尽管这似乎是推荐的方式）。
使用 TypeScript，普通斜体被转换为半粗体斜体。我在 TypeScript 上放置了半粗体声明，但没有在普通斜体中放置。我的 TypeScript 声明和用法：
\definebodyfontenvironment[default][em=italic]
\definebodyfontenvironment[12pt][interlinespace=4.2ex]
\definebodyfontenvironment[10pt][interlinespace=3.2ex]

您必须使用字体 Goodies 才能使用设计尺寸。字体 Goodies 是 Lua 脚本，它返回一个包含有关字体的额外信息的表，并在运行时加载。有关 Goodies 的更多信息，请参阅第 5.4 章“Goodies”ConTeXt 字体 (PDF)。

您可能想要使用除 DejaVu 之外的无衬线字体、单声道字体和数学字体。我只是为了完整性才在这里添加的。您不应该遗漏其中任何一个，因为如果您尝试使用它们并且它们没有定义，就会发生奇怪的事情。
字体替代只能有两个字母，因为 ConTeXt 将使用它后面的任何内容作为大小说明符，就像b中的一样\tfb。
然后您可以通过以下方式在文档中使用它

如您所见，这看起来并不是真正连续的。这是因为我猜测了不同设计尺寸应使用的值。在生产中，应该仔细微调这些值以实现更连续的行为。
输出pdffonts确认所有字体都已嵌入。

系统范围的安装
对于系统范围的安装，您可以将文件放入 ConTeXt 树中的适当位置。我只使用 ConTeXt 安装中的本地树。我显示了所有命令以及它们在我的机器上产生的输出。这些可能当然与您的不同。
首先我们得到本地树的路径，然后我们去那里。
$ mtxrun --resolve-path '$TEXMFLOCAL'
/opt/context/tex/texmf-local
$ cd /opt/context/tex/texmf-local
现在我们为打字稿文件创建一个目录。
$ mkdir -p tex/context/fonts/mkiv/
在这个新目录中，创建两个文件garamond-premier.lfg和，type-imp-garamond-premier.mkiv内容如上所述。
现在我们为 OpenType 字体文件创建一个目录。我遵循目录命名方案的惯例<foundry>/<fontname>。
$ mkdir -p fonts/opentype/adobe/garamond-premier/
将所有 OpenType 文件放在那里。
因为我们在树中添加了新文件，所以我们必须重建文件名数据库。这是使用
$ mtxrun --generate
这将需要一点时间，并向终端打印大量消息。之后，您可以检查树中是否检测到新文件
$ mtxrun --find-file garamond-premier.lfg
/opt/context/tex/texmf-local/tex/context/fonts/mkiv/garamond-premier.lfg
$ mtxrun --find-file type-imp-garamond-premier.mkiv
/opt/context/tex/texmf-local/tex/context/fonts/mkiv/type-imp-garamond-premier.mkiv
$ mtxrun --find-file GaramondPremrPro.otf
/opt/context/tex/texmf-local/fonts/opentype/adobe/garamond-premier/GaramondPremrPro.otf
如果一切正常，您就可以排版文档了。打字稿应该会自动找到\setupbodyfont[garamond-premier]（不需要\usetypescriptfile或类似必要）。
