<title>Character Sets</title>
<para>
<classname>Zend_Mail</classname> does not check for the correct character set of the mail
parts. When instantiating <classname>Zend_Mail</classname>, a charset for the e-mail itself
may be given. It defaults to <emphasis>iso-8859-1</emphasis>. The application has to make
sure that all parts added to that mail object have their content encoded in the correct
character set. When creating a new mail part, a different charset can be given for each
part.

The following example is how to use <classname>Zend_Mail</classname> in Japanese. This
is one of <acronym>CJK</acronym> (aka <acronym>CJKV</acronym> ) languages. If you use
Chinese, you may use <acronym>HZ-GB-2312</acronym> instead of
<acronym>ISO-2022-JP</acronym>.
