Making Microsoft Equation Editor Integral Signs

Question

I tried searching for an answer to the question, but couldn't quite get what I want.

I would like to recreate the integral symbol from Microsoft Equation Editor 3.0 (also known as MathType) in XeLaTex, but I don't know how to do it. (See the image for more info) I'm using the fontspec package and unicode-math.

I have found that the integral symbol is the Unicode integral character ∫ in Times New Roman. However, I don't know how to incorporate this into an equation.

Could you please tell me how I can recreate this equation (exactly)? Thank you in advance.

EDIT:

\documentclass[30pt]{article}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont{Times New Roman}

\begin{document}
The integral character is ∫.
\end{document}

produces

which is the integral sign I want.

Answer 1

You can load individual math symbols and letters from TImes New Roman with the range= option of \setmathfont. I took all others from TeX Gyre Termes Math, including the missing \cdot.

\documentclass{article}
\tracinglostchars=3 % Treat missing characters as errors!
\usepackage{unicode-math}

\defaultfontfeatures{ Scale=MatchLowercase, Ligatures=TeX }

\setmainfont{Times New Roman}
\setmathfont{Tex Gyre Termes Math}
\setmathfont{Times New Roman}[range={
  up, \int}] % Add any nother missing characters here.
\setmathfont{Times New Roman Italic}[range=it]

\begin{document}
\[
\int_5^6 \frac{x\cdot\cos x}{x\cdot\frac{y}{k}}dx
\]
\end{document}

This doesn’t get you a properly-scaling integral, because TImes New Roman doesn’t have a math table, so you might want to leave \int out of rhe range= list. You could also use the font from previous versions of Equation Editor, Cambria Math.

Although this uses the same fonts, you will get slightly-different layout in the two programs.

Another upright integral matching Times that you might try is

\setmathfont{XITS Math}[
  Scale=MatchUppercase,
  range={"222B-"2233,"2A0B-"2A1C},
  StylisticSet=8]

or

\setmathfont{STIX Two Math}[
  Scale=MatchUppercase,
  range={"222B-"2233,"2A0B-"2A1C},
  StylisticSet=8]

If you really, truly want to use an asterisk instead of \cdot or \times, change \cdot to \ast.

Answer 2

The Tex Gyre Termes (text) and TeX Gyre Termes Math (math -- what else?) OpenType fonts may come close enough to qualify as a match.

Note that the following test program requires compilation under XeLaTeX or LuaLaTeX.

\documentclass{article}
\usepackage{unicode-math}
\setmainfont{TeX Gyre Termes}
\setmathfont{TeX Gyre Termes Math}
\begin{document}
\[
\int_5^6 \frac{x\cdot\cos x}{x\cdot\frac{y}{k}}dx
\]
\end{document}
