ctex: macnew 的楷体无法自动使用粗体

[zepinglee]

目前 macnew 的楷体配置是：

\setCJKfamilyfont{zhkai}{Kaiti SC}

然而这样无法自动使用楷体粗体，MWE：

\documentclass[UTF8,fontset=macnew]{ctexart}
\begin{document}
{\kaishu 测试中文 \bfseries 测试中文\par}
\setCJKfamilyfont{zhkai}[BoldFont=Kaiti SC Bold]{Kaiti SC}
{\kaishu 测试中文 \bfseries 测试中文\par}
\end{document}

比较「调用 Songti SC 和 Kaiti SC 时，fontspec 写入日志的信息」后，我倾向于认为问题出在字体文件 Kaiti.ttc 本身。

简化过的 MWE：

\documentclass{article}
\usepackage{fontspec}
\newfontfamily\songti{Songti SC}
\newfontfamily\kaiti{Kaiti SC}
\begin{document}
dummy text
\end{document}

日志中，关于 Songti SC 的部分（注意这里能自动获取 bold series 等的字体信息）：

.................................................
. fontspec info: "no-font-shape"
. 
. Could not resolve font "Songti SC/I" (it probably doesn't exist).
.................................................
