==== UTF-8 Environment for Ubuntu Server ====
<code>
echo "en_US.UTF-8 UTF-8" > /var/lib/locales/supported.d/local
locale-gen
update-locale LANG=en_US.UTF-8
</code>
Note: For some VPS the last command does not work, you have to add this to ~/.bashrc or /etc/bash.bashrc too:
<code>
export LANG=en_US.UTF-8
</code>

==== Pinyin Sorting for non-Chinese Locales ====
Arch:
<code>
echo "LC_COLLATE=zh_CN.utf8" >> /etc/locale.conf
</code>
Ubuntu:
<code>
echo "LC_COLLATE=zh_CN.utf8" >> /etc/default/locale
</code>
