Marujirushi symbol won't display using Xelatex

Question

I'm using Xelatex. I'm trying to type the Japanese marujirushi symbol into my document. The exact way I get the symbol is to toggle my keyboard to the Microsoft Japanese IME, type maru, hit the spacebar and select ○　丸印. If I type it into Google, it tells me the character is Unicode Character 'WHITE CIRCLE' (U+25CB).

I tried \textbigcircle from the textcomp package, but it also didn't work. However, I don't think that character is the right size, so I don't want it.

I also thought it might be a font issue, but I was using MS Mincho and it shows up fine in Microsoft Word. So I assume it would show up in my document too.

More context: I'm writing a document with both Latin letters and CJK. xeCJK used one font for the Latin letters and MS Mincho for the Japanese characters. I'd like to be able to retain that.

How can I get this character to display in my document?

Here is my example:

\documentclass{article}
\usepackage[boldfont]{xeCJK}
\setCJKmainfont{MS Mincho}

\begin{document}

    ○ Keyboard input of ``marujirushi"

\end{document}

Here is a list of packages that I'm using in my document, for context:

\usepackage[boldfont]{xeCJK}
\usepackage{makecell}
\usepackage{csquotes}
\usepackage{tabularx}
\usepackage{multirow}
\usepackage{graphicx}
\usepackage{longtable}
\usepackage{titlesec}
\usepackage{ruby}
\usepackage{textcomp}
\usepackage{tipa}

Answer 1

The character does not belong to the CJK family, so xeCJK will print it in the Latin family and the default Latin Modern hasn't it.

You have two strategies:

1. define as main (Latin) font one that has the glyph (it could be the same font you use for CJK glyphs, if it supports Latin)
2. redefine the character to issue a command for selecting the CJK font

You can also combine the two by defining a font that has the glyph.

First strategy

\documentclass{article}
\usepackage{xeCJK}

\setCJKmainfont{Hiragino Mincho Pro W3} % or whatever
\setmainfont{Hiragino Mincho Pro W3}

\begin{document}

○ Keyboard input of ``marujirushi"

\end{document}

Second strategy

\documentclass{article}
\usepackage{xeCJK}

\usepackage{newunicodechar}

\setCJKmainfont{Hiragino Mincho Pro W3} % or whatever

\ExplSyntaxOn
\newunicodechar{○}{{\xeCJK_select_font: ○}}
\ExplSyntaxOff

\begin{document}

○ Keyboard input of ``marujirushi"

\end{document}

Combined strategy

\documentclass{article}
\usepackage{xeCJK}

\usepackage{newunicodechar}

\setCJKmainfont{Hiragino Mincho Pro W3} % or whatever
\newfontfamily{\maru}{Hiragino Mincho Pro W3} % or whatever

\newunicodechar{○}{{\maru ○}}

\begin{document}

○ Keyboard input of ``marujirushi"

\end{document}

Note

As I don't have MS Mincho, I used a different CJK font, but it should be irrelevant.

Different strategy (caveat: no real testing done)

Use `\xeCJK_select_font:

\documentclass{article}
\usepackage{xeCJK}

\usepackage{newunicodechar}

\setCJKmainfont{Hiragino Mincho Pro W3} % or whatever

\ExplSyntaxOn
\newunicodechar{○}{{\normalfont\xeCJK_select_font: ○}}
\ExplSyntaxOff

\begin{document}

○ Keyboard input of ``marujirushi"

\end{document}

Be aware that no real testing has been done, as I know no Japanese, Chinese or Korean.

Answer 2

Without using the CJK setting it works:

\documentclass{article}
\usepackage{fontspec}
%\usepackage[boldfont]{xeCJK}
%\setCJKmainfont{MS Mincho}
\setmainfont{MS Mincho}

\begin{document}

    ○ Keyboard input of ``marujirushi"

\end{document}

or alternatively:

\documentclass{article}
\usepackage{xeCJK}
\setCJKmainfont{MS Mincho}
\newfontface\Mincho{MS Mincho}

\begin{document}

    {\Mincho○} Keyboard input of ``marujirushi"

\end{document}
