用 boisik 支撑底部

Question

有没有办法让 underbrace 与 boisik 一起工作？这是一个最小的非工作示例：

\documentclass[english,a4paper,11pt]{article}
\usepackage{boisik}
\usepackage[OT1]{fontenc}
\usepackage[utf8]{inputenc}

\begin{document}
\[
\underbrace{xx}_{xx}
\]
\end{document}

结果如下所示（我使用 pdfLaTeX 作为编译器）：

Answer 1

你得到

Missing character: There is no z in font bskex10!
Missing character: There is no | in font bskex10!
Missing character: There is no { in font bskex10!
Missing character: There is no z in font bskex10!
Missing character: There is no } in font bskex10!

您可以通过导入标准字形来恢复丢失的字形。

\documentclass{article}
\usepackage{boisik}

\DeclareSymbolFont{cmlargesymbols}{OMX}{cmex}{m}{n}
\DeclareMathSymbol{\braceld}{\mathord}{cmlargesymbols}{"7A}
\DeclareMathSymbol{\bracerd}{\mathord}{cmlargesymbols}{"7B}
\DeclareMathSymbol{\bracelu}{\mathord}{cmlargesymbols}{"7C}
\DeclareMathSymbol{\braceru}{\mathord}{cmlargesymbols}{"7D}

\begin{document}
\[
\underbrace{xxxxxxxx}_{xx} \quad \overbrace{xxxxxxxx}^{xx}
\]
\end{document}

不过，您必须意识到这boisik仅适用于位图格式……
