Send Chinese Email

C# example code showing how to send email using gb2312 or big5.

	bool success = false;

	// Create a mailman object for sending email.
	Chilkat.MailMan mailman = new Chilkat.MailMan();

	// Any string argument automatically begins the 30-day trial.
	mailman.UnlockComponent("30-day trial");

	// Set the SMTP server.
	mailman.SmtpHost = "smtp.earthlink.net";

	// Create an email object
	Chilkat.Email email = new Chilkat.Email();

	// Set the basic email stuff: body, subject, "from", "to"
	// (This C# source code file was saved as Unicode.)
	email.Body = "香 港 剛 結 束 長 達 五 年 多";
	email.Subject = "香 港 剛 結 束 長 達 五 年 多";
	email.AddTo("五 年 多","support@chilkatsoft.com");
	email.From = "五 年 多 <programmer@chilkatsoft.com>";

	// Chilkat automatically recognizes that this email has Chinese characters,
	// and thus encodes everything as it is needed for the default Chinese encoding
	// of gb2312.
	// It is possible to verify this by examining the full MIME text of the email:
	MessageBox.Show(email.GetMime());

	// The MIME that Chilkat generates for this email looks like this:
	/*
