Local $bSuccess

$oEmail = ObjCreate("Chilkat.Email")

; Tell Chilkat you want the email to be utf-8.
$oEmail.Charset = "utf-8"

$oEmail.From = "somebody@gmail.com"
$oEmail.AddTo("Joe","joe_somebody@gmail.com")
$oEmail.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
; 
$oSbHtml = ObjCreate("Chilkat.StringBuilder")
$oSbHtml.LoadFile("qa_data/html/sample_utf8.html","utf-8")

$oEmail.SetHtmlBody $oSbHtml.GetAsString()

; If this email was sent as-is, it would look like this:
$oMailman = ObjCreate("Chilkat.MailMan")
ConsoleWrite($oMailman.RenderToMime($oEmail) & @CRLF)

; The MIME that would be sent is this:

; Let's say we want to send iso-8859-1 instead...
; Just set the email object's Charset property, like this:
$oEmail.Charset = "iso-8859-1"

; Now see what would be sent:

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

$oEmail.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).  
; However, the email would still be sent correctly.)
