Usually, every software package has its own message domain.</p> <!-- INDENTATION --> <p>By default, the <b>gettext</b> family of functions returns translated messages in the locale’s character encoding, which can be retrieved as <b>nl_langinfo(CODESET)</b>. The need for calling <b>bind_textdomain_codeset</b> arises for programs which store strings in a locale independent way (e.g. UTF-8) and want to avoid an extra character set conversion on the returned translated messages.</p> <!-- INDENTATION --> <p><i>domainname</i> must be a non-empty string.</p> <!-- INDENTATION --> <p>If <i>codeset</i> is not NULL, it must be a valid encoding name which can be used for the <b>iconv_open</b> function. The <b>bind_textdomain_codeset</b> function sets the output codeset for message catalogs belonging to domain <i>domainname</i> to <i>codeset</i>. The function makes copies of the argument strings as needed.</p> <!-- INDENTATION --> <p>If <i>codeset</i> is NULL, the function returns the previously set codeset for domain <i>domainname</i>.
