Demonstrates how to specify the character encoding (charset) to be used for the body of an HTTP POST. AutoIt

; This example requires the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.

; Add the request params expected by the server-side:
$oReq.AddParam "tytul",$oJson.StringOf("tytul")
$oReq.AddParam "tresc",$oJson.StringOf("tresc")

; Indicate we wish to explicitly send the charset attribute in the HTTP request header.
$oReq.SendCharset = True

; Send the POST
; You can send the POST to the URL below.  It will respond with the request body in quoted-printable format.
; Using quoted-printable, we can easily see the binary bytes for the accented chars.

$oReq.HttpVerb = "POST"
$oReq.ContentType = "application/x-www-form-urlencoded"

; Sample output:

; --------------------------------------------------
; POST /echoPost.cshtml HTTP/1.1
; Host: www.chilkatsoft.com
; Content-Type: application/x-www-form-urlencoded; charset=utf-8
; Content-Length: 79
; 
; <pre>tytul=3DPrzyk%C5%82ad&amp;tresc=3DPrzyk%C5%82ad
; %82oszenie</pre>
; --------------------------------------------------

; We can see by the %C5%82 that utf-8 was sent, because %C5%82 is the 2-byte representation of a particular Polish char.

; -----------------------
; However.. we can change the charset used for the HTTP request by specifying the request object's charset.

$oReq.SendCharset = True
$oReq.Charset = "windows-1250"
$oReq.HttpVerb = "POST"

    Exit
EndIf

ConsoleWrite($oHttp.LastHeader & @CRLF)
ConsoleWrite($oResp.BodyStr & @CRLF)

; Sample output...
; You can see how the bytes used for the Polish chars are now 1-byte per char (i.e. using Windows-1250)
