By default, it will not support double byte characters, But a couple of simple changes will make this work.
On each of the pages, you will need to change the content type meta tag to use the character set you wish to use, for example, to use the korean character set, change:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
to:
<meta http-equiv="Content-Type" content="text/html; charset=ISO-2022-KR" />
then in the WA_Universal_Email/WAUE_contact_1.php file, find the following line:
$WA_MailObject = WAUE_Definition("".($WAGLOBAL_Email_Server) ."","25","","","","");
and change it to use your preferred character set, for Korean:
$WA_MailObject = WAUE_Definition("".($WAGLOBAL_Email_Server) ."","25","","","","ISO-2022-KR");
Sorry, we do not offer demos.
