我已经下载了这两种字体:

我运行fc-cache -f -v,所以fc-list知道这些字体。

fc-list | grep '\.fonts' | grep 'NotoSansMonoCJKsc'
/home/rodrigo/.fonts/NotoSansMonoCJKsc-VF.otf: Noto Sans Mono CJK SC:style=Medium
/home/rodrigo/.fonts/NotoSansMonoCJKsc-Regular.otf: Noto Sans Mono CJK SC:style=Regular
/home/rodrigo/.fonts/NotoSansMonoCJKsc-VF.otf: Noto Sans Mono CJK SC
/home/rodrigo/.fonts/NotoSansMonoCJKsc-VF.otf: Noto Sans Mono CJK SC:style=Bold
/home/rodrigo/.fonts/NotoSansMonoCJKsc-VF.otf: Noto Sans Mono CJK SC:style=Regular

使用时NotoSansMonoCJKsc-Regular.otf,文档编译没有问题。

我猜想发生这种情况是因为xelatex尚不支持可变字体。

如果xelatex支持可变字体,有人能告诉我为什么我的系统在尝试编译文档时显示这些错误吗?

如果xelatex不支持可变字体,如果有人可以提供可靠的来源说明这一点或源代码中的某些部分以便我得出这一结论,我将不胜感激。

附加信息

VF对于那些不知道文件名中的含义的人来说NotoSansMonoCJKSC-VF,它代表“可变字体”(维基百科文章链接)

我发现这个问题在 lists.fedoraproject.org 邮件列表中提到了使用可变字体编译文档的相同问题xelatex

下面显示的代码块显示了的版本xelatex,我用它来编译上面显示的两个文档。

答案1

阅读fontspec文档后,似乎只有 LuaLaTeX 支持可变字体;fontspec最近在 2.9a 版本中添加了对它们的支持。

答案2

根据文档,当前fontspecXeTeX 支持 Multiple Master 字体,但不支持 Variable 字体,而 LuaTeX 支持 Variable 字体但不支持 Multiple Master 字体。

fontspec.pdf第 7 节第 32 页:

目前 OpenType 可变字体仅支持 LuaTeX,而 Multiple Master 字体仅适用于 XeTeX。

fontspec2024/02/13 v2.9a

这是目前 CTAN 上的版本fontspec(2024-04-27)。
