因为手机短消息的发送是以PDU串的形式发送出去的，中文字符以Unicode码来表示，所以在发送中文短消息之前必须首先将中文字符转换为Unicode码，下面的函数将实现这个功能。这个函数主要应用到VB自带的一个格式转换函数：AscW（）将中文转换为Unicode码-because phone short message is sent in the form of Series PDU sent, Chinese characters in Unicode code to indicate, Therefore, the Chinese short message sent before the Chinese must first be converted to Unicode character codes, the following function to achieve this function. The main function of the VB application onboard a format conversion functions : AscW () will be converted to Unicode Chinese code
