_INetSmtpMail wont send national characters

[VojtechPechar]

Hello,

I have a script with _INetSmtpMail. Generaly same as example

#include <INet.au3>

$s_SmtpServer = "mysmtpserver.com.au"
$s_FromName = "My Name"
$s_FromAddress = "From eMail Address"
$s_ToAddress = "To eMail Address"
$s_Subject = "My Test UDF"
Dim $as_Body[2]
$as_Body[0] = "Testing the new email udf"
$as_Body[1] = "Second Line"
$Response = _INetSmtpMail ($s_SmtpServer, $s_FromName, $s_FromAddress, $s_ToAddress, $s_Subject, $as_Body)
$err = @error
If $Response = 1 Then
    MsgBox(0, "Success!", "Mail sent")
Else
    MsgBox(0, "Error!", "Mail failed with error code " & $err)
EndIf

It works fine, but it is not able to handle national characters

This

příliš žluťoučký kůň úpěl ďábelské ódy

comes as

p??li? ?lu?ou?k? k?? ?p?l ??belsk? ?dy

So my thoughts were - I am running quite old Autoit version 3.3.6.1 I should update it. I did that to latest possible and ooops the example script does not work anymore with

_inetsmtpmail error code 4

#include <Inet.au3>
#include <MsgBoxConstants.au3>

Local $s_SmtpServer = "mysmtpserver.com.au"
Local $s_FromName = "My Name"
Local $s_FromAddress = "From eMail Address"
Local $s_ToAddress = "To eMail Address"
Local $s_Subject = "My Test UDF"
Local $as_Body[2]
$as_Body[0] = "Testing the new email udf"
$as_Body[1] = "Second Line"
Local $iResponse = _INetSmtpMail($s_SmtpServer, $s_FromName, $s_FromAddress, $s_ToAddress, $s_Subject, $as_Body)
Local $iErr = @error
If $iResponse = 1 Then
    MsgBox($MB_SYSTEMMODAL, "Success!", "Mail sent")
Else
    MsgBox($MB_SYSTEMMODAL, "Error!", "Mail failed with error code " & $iErr)
EndIf

Any tips how to fix this or troubleshoot that? Unfortunately I have no access to smtp server...

Thanks for tips
