# Typesetting furigana above and below original text

I have followed Japanese Problem using MacTeX 2011 to set up Ruby Furigana with TeX.

I'm wondering if it is possible to set up Furigana both above and below the original character?

Thanks, I'm a total newbie in TeX, but furigana support totally sucks everywhere else, apparently... –  Vasili Sviridov Jan 28 '13 at 18:38
Are Furigana really used both above and below? –  egreg Jan 28 '13 at 18:40
W3C guidelines for Ruby text do suggest the ability for simultaneous usage, and wikipedia article on the subject also seem to have it in some way... But I want it to help with my studies, not for publishing purposes. –  Vasili Sviridov Jan 28 '13 at 18:43

It seems that you can set the \rubysep parameter to a negative value to get the effect you want.

%!TEX TS-program = xelatex
\documentclass[12pt]{article}

\usepackage{xeCJK}
\usepackage{ruby}
\setCJKmainfont{Hiragino Mincho Pro}
\renewcommand{\rubysep}{-4ex}
\pagestyle{empty}
\begin{document}

On this line \ruby{学}{がく}\ruby{生}{せい}

\end{document}


Here's a solution which seems to allow simultaneous top and bottom furigana

%!TEX TS-program = xelatex
\documentclass[24pt]{letter}
\usepackage{xeCJK}
\usepackage{ruby}
\setCJKmainfont{Hiragino Kaku Gothic ProN}
\usepackage{setspace}
\usepackage[margin=0.2in]{geometry}
%%
\makeatletter
\newcommand{\defaultrubysep}{0.25ex}
\renewcommand{\rubysep}{\defaultrubysep}
\newcommand{\english}{}
\renewcommand{\english}{-3.2ex}
\newlength{\kanji@kana@no@nagasa}
\newcommand{\eruby}[3]{%
%% save the current baselinestretch
%% and reset value to "1"
\let\oldbaselinestretch=\baselinestretch%
\renewcommand{\baselinestretch}{1}%
\large\normalsize%
\ruby{#1}{#2}%
%% reassign \rubysep to allow furigana below
\renewcommand{\rubysep}{\english}%
%% measure the width of the first argument
%% move to the left by that distance
\settowidth{\kanji@kana@no@nagasa}{#1}%
\hspace*{\dimexpr-\kanji@kana@no@nagasa\relax}%
\ruby{\phantom{#1}}{#3}%
%% restore the original \rubysep and \ baselinestretch
\renewcommand{\rubysep}{\defaultrubysep}%
\renewcommand{\baselinestretch}{\oldbaselinestretch}
\large\normalsize%
}
\makeatother
%%
\pagestyle{empty}
\begin{document}
%% implement double spacing
\renewcommand{\baselinestretch}{2}\large\normalsize

たんぼの　\eruby{畦道}{あぜみち}{footpath}に、\eruby{タンポポ}{tanpopo}{dandelion}が

\begin{tabular}{rl}

This produces:

The idea is two first save the current \baselinestretch and then reset to 1. Then I call \ruby{...} twice, the second time using a \phantom argument and adding a negative width between the two calls to \ruby to give the appearance of two furiganas for one block of kanji or other kana.

Since ruby is scaling things vertically based upon baseline values, I think all your vertical scaling should do the same thing.

But is it possible to have them both simultaneously? I'm trying to have the kana above and the english version below the kanji characters, for my studies. –  Vasili Sviridov Jan 28 '13 at 18:40
Thank you so much! –  Vasili Sviridov Jan 29 '13 at 5:02
I've tried it out, but there are still some issues (possibly due to my misunderstanding of the TeX inner works). Could you take a look at gist.github.com/4662109? If I use the double spacing - it gets all screwed up. Which could be fixed by playing with the offsets, I guess. But it also pushes the following character to the right. Also, how would one change the type for the english portion? Japanese types have monospaced font for english letters. Thanks. –  Vasili Sviridov Jan 29 '13 at 5:46
Cute story. I'll have to think about this one. I might not have an answer until later tomorrow. –  A.Ellett Jan 29 '13 at 5:52
Thank you again, you are very helpful. –  Vasili Sviridov Jan 29 '13 at 5:54
