　こんな夢を見た。\\
六つになる子供を負ってる。たしかに自分の子である。ただ不思議な事に
はいつの間にか眼が潰れて、青坊主になっている。自分が御前の眼はいつ
潰れたのかいと聞くと、なに昔からさと答えた。声は子供の声に相違ない
が、言葉つきはまるで大人である。しかも対等だ。左右は青田である。路
は細い。鷺の影が時々闇に差す。

===== google/adobe fonts =====
Google/adobe released pan-cjk fonts, yet its still complicated to get them to work wit tex.
  * https://github.com/adobe-fonts/source-han-sans -- the font
===== attempt to use the fonts in xetex on Fedora21 =====
This does not work for me currently. The fonts are installed and available in "fc-list | grep -i source", but rendering with xetex fails. Installing the fonts is easy since Fedora20:
<code>
yum install adobe-source-code-pro-fonts
[root@спутник ~]# fc-list |grep -i sourcecode
/usr/share/fonts/adobe-source-code-pro/SourceCodePro-Bold.otf: Source Code Pro:style=Bold
/usr/share/fonts/adobe-source-code-pro/SourceCodePro-Regular.otf: Source Code Pro:style=Regular
/usr/share/fonts/adobe-source-code-pro/SourceCodePro-Medium.otf: Source Code Pro,Source Code Pro Medium:style=Medium,Regular
/usr/share/fonts/adobe-source-code-pro/SourceCodePro-Light.otf: Source Code Pro,Source Code Pro Light:style=Light,Regular
/usr/share/fonts/adobe-source-code-pro/SourceCodePro-Black.otf: Source Code Pro,Source Code Pro Black:style=Black,Regular
/usr/share/fonts/adobe-source-code-pro/SourceCodePro-ExtraLight.otf: Source Code Pro,Source Code Pro ExtraLight:style=ExtraLight,Regular
/usr/share/fonts/adobe-source-code-pro/SourceCodePro-Semibold.otf: Source Code Pro,Source Code Pro Semibold:style=Semibold,Regular
</code>

Trying to use the fonts:
<code>
% compile with: xelatex file.tex
\documentclass{article}

\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}

\setmainfont{SourceHanSansJP-Medium}
