僅從 mtpro 中取得積分和求和符號，並在 unicode 設定中使用 lualatex

Question

從 mathtime 字型中取得積分符號（\int、\oint、\iint 等）和求和符號，但使用 unicode 字型和 unicode-math 的工作策略是什麼？應該有辦法，但我想不通。有任何想法嗎？

Answer 1

你可以這樣做：

\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}

為了測試，我實際上使用了

\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所以我可以使用或進行相同的排版lualatex並比較輸出，這似乎是相同的（已使用獨特的數學字體進行檢查）。

警告。其他一些符號可能需要處理。
