(JavaScript) Controlling Charset of HTML Email
This example demonstrates how to change the charset of an HTML email by setting the Charset property.
var success = false;
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
var email = new CkEmail();
// Tell Chilkat you want the email to be utf-8.
email.Charset = "utf-8";
email.From = "somebody@gmail.com";
email.AddTo("Joe","joe_somebody@gmail.com");
email.Subject = "This is a test";
// Load a utf-8 HTML file that will be the body of this email.
// The HTML contains this line to specify the charset:
//
// <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
//
// The sample HTML is available here: https://chilkatsoft.com/exampleData/sample_utf8.html
//
var sbHtml = new CkStringBuilder();
sbHtml.LoadFile("qa_data/html/sample_utf8.html","utf-8");
email.SetHtmlBody(sbHtml.GetAsString());
// If this email was sent as-is, it would look like this:
var mailman = new CkMailMan();
console.log(mailman.RenderToMime(email));
// The MIME that would be sent is this:
// MIME-Version: 1.0

// -----------------------------------------
// Let's say we want to send iso-8859-1 instead...
// Just set the email object's Charset property, like this:
email.Charset = "iso-8859-1";
// Now see what would be sent:
console.log(mailman.RenderToMime(email));
// MIME-Version: 1.0

// Let's say we don't want quoted-printable, but instead want 8bit.

email.AddHeaderField("Content-Transfer-Encoding","8bit");
// Now see what would be sent:
// (Note: Because RenderToMime returns a string, it generally not possible to render MIME to a string
// IF the MIME contains binary data and uses the 8bit encoding (for example, if a JPEG image was attached).
