how to represent these symbols from Word in LaTeX?

Question

\scriptP in Word,

\scriptp in Word.

What are the representations in LaTeX?

Answer 1

The default math font in Word in Cambria. If you use Cambria, then these symbols are available. I show how to use Cambria with ConTeXt and perhaps someone could add how to use it in LuaLaTeX and XeLaTeX.

\setupbodyfont[cambria]
\starttext
${\cal Pp}$
\stoptext

which gives

Answer 2

Here's the LuaLaTeX/XeLaTeX analogue to Aditya's conTeXt-based answer. Observe the use of the Cambria Math math font and the \mathscr ("script math") macro.

Incidentally, the third character shown below, sometimes (frequently??) called "Weierstrass-p", is available in basic LaTeX -- no need to employ the Cambria Math Opentype font...

%%% compile with either LuaLaTeX or XeLaTeX
\documentclass{article}
\usepackage{unicode-math}
\setmainfont{Cambria} % optional
\setmathfont{Cambria Math}

\begin{document}
$\mathscr{P}$ $\mathscr{p}$ $\wp$
\end{document}

Answer 3

It strongly depends on what you want to achieve.

If it's lower case calligraphic letters you are after try.

\usepackage{dutchcal}

\begin{document}
  pP $pP \; \mathcal{pP}$
\end{document}

If you go down this road checkout this question.

If you want to typeset all math in 'Cambria Math' you need to use XeLaTeX or LuaLaTeX. (see here)

A simple implementation could be

\usepackage{fontspec}
\usepackage{unicode-math}
\setmathfont{STIX Two Math}

\begin{document}
  pP $pP \; \mathscr{pP}$
\end{document}

Note the use of \mathscr instead of \mathcal as the latter does only provide upper case calligraphic variants.

I do not have 'Cambria Math' installed on my system so I can only provide a screenshot with 'Stix 2'.

Answer 4

\documentclass{article}
\usepackage{mathrsfs}

\begin{document}
$\mathscr{P}\quad \wp$
\end{document}
