# How to put CJK in subscript

I want to put a hiragana character in subscript.
I have this:

\documentclass[a4paper,fontsize=13pt]{scrartcl}

\usepackage{xeCJK}

\setmainfont[Mapping=tex-text]{Ubuntu}
\setCJKmainfont{VL Gothic}

\begin{document}

V$_{\text{る}}$

\end{document}


but get

! Undefined control sequence.
l.10 V$_{\text {る}}$

The \text command requires amsmath (or amstext that's automatically loaded by amsmath). However, for textual subscripts there is \textsubscript.

I changed the fonts to ones I have, just to show the output.

\documentclass[a4paper,fontsize=13pt]{scrartcl}

\usepackage{fix-cm} % to turn off annoying warnings

\usepackage{xeCJK}

\setmainfont{Libertinus Serif}
\setCJKmainfont{Heiti SC}

\begin{document}

V\textsubscript{る}

\end{document}

• @Au101 Sorry, but I don't understand – egreg Jul 20 '16 at 0:11
• That's the URL of the png image you uploaded showing the output. The long series of qs, plus the roundedness of the o and the qs - it just struck me as a very pleasing random series of letters, the kind of URL you wouldn't get very often, since I assume they're just generated sequences of letters. But I'm just that sort of sad person who notices that kind of thing. Like when the time is 11:11:11, or when it was the 12th of December 2012 (12/12/12). Shrug. Anyway – Au101 Jul 20 '16 at 0:19
