I ve downloaded the phpmailer! When the email [b]subject [/b]is in traditional chinese character, it cannot display properly Gmail. (The content is fine if it is also in traditional chinese character.) And I tried to just use the php function [b]mail()[/b], it did work in chinese character. However, i need the email content to be in HTML, so, i added headers in the function mail(), headers = "X-Mailer: PHP/" . phpversion() . "\r\n" . "MIME-Version: 1.0\r\n" . "Content-Type: text/html; charset=utf-8\r\n" . "Content-Transfer-Encoding: 7bit\r\n\r\n"; it got even bad, that is, cannot display both chinese character and HTML content. I have to work it for whole day, and still havent get a solution to it. Could anyone know how to solve it?? thanks!!
