仅从 mtpro 中获取积分和求和符号，并使用 unicode 设置中的 lualatex

Question

有什么可行的策略可以从 mathtime 字体中获取积分符号 (\int、\oint、\iint 等) 和求和符号，但除此之外还要使用 unicode 字体和 unicode-math？应该有办法，但我搞不清楚。有什么想法吗？

Answer 1

您可以执行以下操作：

\documentclass{article}
\usepackage{amsmath}
\usepackage{unicode-math}

\DeclareFontEncoding{LMP3}{}{}
\DeclareFontSubstitution{LMP3}{mtt}{m}{n}
\DeclareFontFamily{LMP3}{mtt}{}
\DeclareFontShape{LMP3}{mtt}{m}{n}{<->mt2exa}{}
\DeclareSymbolFont{mtprolargesymbols}{LMP3}{mtt}{m}{n}

\makeatletter
\AtBeginDocument{%
  \renewcommand{\sum}{\DOTSB\sum@\slimits@}%
  \renewcommand{\prod}{\DOTSB\prod@\slimits@}%
  \DeclareMathSymbol{\intop}{\mathop}{mtprolargesymbols}{"52}%
  \DeclareMathSymbol{\iintop}{\mathop}{mtprolargesymbols}{"92}%
  \DeclareMathSymbol{\iiintop}{\mathop}{mtprolargesymbols}{"94}%
  \DeclareMathSymbol{\ointop}{\mathop}{mtprolargesymbols}{"48}%
  \DeclareMathSymbol{\oiintop}{\mathop}{mtprolargesymbols}{"96}%
  \DeclareMathSymbol{\oiiintop}{\mathop}{mtprolargesymbols}{"98}%
  \DeclareMathSymbol{\cwointop}{\mathop}{mtprolargesymbols}{"9A}%
  \DeclareMathSymbol{\awointop}{\mathop}{mtprolargesymbols}{"9C}%
  \DeclareMathSymbol{\cwintop}{\mathop}{mtprolargesymbols}{"9E}%
  \DeclareMathSymbol{\barintop}{\mathop}{mtprolargesymbols}{170}%
  \DeclareMathSymbol{\slashintop}{\mathop}{mtprolargesymbols}{172}%
  \DeclareMathSymbol{\sum@}{\mathop}{mtprolargesymbols}{"50}%
  \DeclareMathSymbol{\prod@}{\mathop}{mtprolargesymbols}{"51}%
  \def\iint{\DOTSI\iintop\ilimits@}%
  \def\iiint{\DOTSI\iiintop\ilimits@}%
  \def\oiint{\DOTSI\oiintop\ilimits@}%
  \def\oiiint{\DOTSI\oiiintop\ilimits@}%
  \def\cwoint{\DOTSI\cwointop\ilimits@}%
  \def\awoint{\DOTSI\awointop\ilimits@}%
  \def\cwint{\DOTSI\cwintop\ilimits@}%
  \def\barint{\DOTSI\barintop\ilimits@}%
  \def\slashint{\DOTSI\slashintop\ilimits@}%
  \def\slsum{\DOTSB\slsumop\slimits@}%
  \def\slprod{\DOTSB\slprodop\slimits@}%
  \def\slcoprod{\DOTSB\slcoprodop\slimits@}%
  \def\upsum{\DOTSB\upsumop\slimits@}%
  \def\upprod{\DOTSB\upprodop\slimits@}%
  \def\upcoprod{\DOTSB\upcoprodop\slimits@}%
}
\makeatother

\begin{document}

$\int\oint\iint\sum\prod$

\[\int\oint\iint\sum\prod\]

\end{document}

为了测试，我实际上使用了

\documentclass{article}
\usepackage{iftex}
\usepackage{amsmath}

\ifluatex
\usepackage{unicode-math}
\usepackage{kpfonts-otf}

\DeclareFontEncoding{LMP3}{}{}
\DeclareFontSubstitution{LMP3}{mtt}{m}{n}
\DeclareFontFamily{LMP3}{mtt}{}
\DeclareFontShape{LMP3}{mtt}{m}{n}{<->mt2exa}{}
\DeclareSymbolFont{mtprolargesymbols}{LMP3}{mtt}{m}{n}

\makeatletter
\AtBeginDocument{%
  \renewcommand{\sum}{\DOTSB\sum@\slimits@}%
  \renewcommand{\prod}{\DOTSB\prod@\slimits@}%
  \DeclareMathSymbol{\intop}{\mathop}{mtprolargesymbols}{"52}%
  \DeclareMathSymbol{\iintop}{\mathop}{mtprolargesymbols}{"92}%
  \DeclareMathSymbol{\iiintop}{\mathop}{mtprolargesymbols}{"94}%
  \DeclareMathSymbol{\ointop}{\mathop}{mtprolargesymbols}{"48}%
  \DeclareMathSymbol{\oiintop}{\mathop}{mtprolargesymbols}{"96}%
  \DeclareMathSymbol{\oiiintop}{\mathop}{mtprolargesymbols}{"98}%
  \DeclareMathSymbol{\cwointop}{\mathop}{mtprolargesymbols}{"9A}%
  \DeclareMathSymbol{\awointop}{\mathop}{mtprolargesymbols}{"9C}%
  \DeclareMathSymbol{\cwintop}{\mathop}{mtprolargesymbols}{"9E}%
  \DeclareMathSymbol{\barintop}{\mathop}{mtprolargesymbols}{170}%
  \DeclareMathSymbol{\slashintop}{\mathop}{mtprolargesymbols}{172}%
  \DeclareMathSymbol{\sum@}{\mathop}{mtprolargesymbols}{"50}%
  \DeclareMathSymbol{\prod@}{\mathop}{mtprolargesymbols}{"51}%
  \def\iint{\DOTSI\iintop\ilimits@}%
  \def\iiint{\DOTSI\iiintop\ilimits@}%
  \def\oiint{\DOTSI\oiintop\ilimits@}%
  \def\oiiint{\DOTSI\oiiintop\ilimits@}%
  \def\cwoint{\DOTSI\cwointop\ilimits@}%
  \def\awoint{\DOTSI\awointop\ilimits@}%
  \def\cwint{\DOTSI\cwintop\ilimits@}%
  \def\barint{\DOTSI\barintop\ilimits@}%
  \def\slashint{\DOTSI\slashintop\ilimits@}%
  \def\slsum{\DOTSB\slsumop\slimits@}%
  \def\slprod{\DOTSB\slprodop\slimits@}%
  \def\slcoprod{\DOTSB\slcoprodop\slimits@}%
  \def\upsum{\DOTSB\upsumop\slimits@}%
  \def\upprod{\DOTSB\upprodop\slimits@}%
  \def\upcoprod{\DOTSB\upcoprodop\slimits@}%
}
\makeatother
\else
\usepackage[lite]{mtpro2}
\fi

\begin{document}

$\int\oint\iint\sum\prod$

\[\int\oint\iint\sum\prod\]

\end{document}

pdflatex所以我可以使用或排版相同的lualatex内容并比较输出，它们似乎是相同的（检查时使用了独特的数学字体）。

警告。其他一些符号可能需要处理。
