Hi,
I have a little problem with aspose email (.net 4.0, version 1.9.0.0) merge function: the accented characters are replaced with question marks ‘?’ when I do a merge.
Here is some code:
TemplateEngine engine = new TemplateEngine(_myMailMessage);
MailMessageCollection __mergedMessageCollection = engine.Instantiate(_datasetParticipantInfos.Tables[“General”]);
_myMailMessageMerged = __mergedMessageCollection[0];
- _myMailMessage is a MailMessage with some ‘mergefields’ like ‘#FirstName#’
- _datasetParticipantInfos.Tables[“General”] contains the infos to merge with, coming from sql storred proc
When I do merge with ‘normal characters’, it just works. My problem occurs when I try to merge with accented characters (é, è, ô): all these are replaced with ‘?’.
I’ve tried to set the _myMailMessage.preferedEncoding and myMailMessageMerged.preferedEncoding to “UTF8” or “Unicode”, but the result is the same.
While debuging in Visual Studio, i can see this in the ‘engine’ value:
"Subject: Rejected email subject #FirstName# #LastName# \r\nFrom: test@sharpdev.com\r\nTo: p@gmail.com\r\nMIME-Version: 1.0\r\nContent-Type: multipart/alternative;\r\n boundary="–=NextPart0_f86c5f24-eb99-4d05-b0c9-9b1739715bf2"\r\n\r\n\r\n----=NextPart0_f86c5f24-eb99-4d05-b0c9-9b1739715bf2\r\nContent-Type: text/plain; charset=us-ascii\r\nContent-Transfer-Encoding: quoted-printable\r\n\r\nHello #FirstName# #LastName#,

\r\n----=_NextPart0_f86c5f24-eb99-4d05-b0c9-9b1739715bf2–\r\n\r\n"
the ’
TemplateEngine ’ seems to be set to ASCII encoding, and I can’t see any public property of the TemplateEngine where I could change the encoding to UTF8. And I don’t know if that would be a solution to my problem.
I’m also using Aspose Words with MailMerge based on the same dataset, and I don’t have that kind of problems with the accented characters.
Thank you
Hi Jerome,
Thank you for using Aspose.Email.
I can notice/reproduce the issue at my end using Mail merge with Data table. I have forwarded these details to our development team for further investigation. Once the issue is resolved or we have any update from our development team, we will let you know here. We appreciate your patience in this regard.
The issue has been logged in our Issue Tracking System as: NETWORKNET-33372.
Hello,
We’ve been able to resolve part of this problem by setting the MailMessage.BodyEncoding Encoding to 'Encoding.GetEncoding(1252)" just after the creation of the mailMessage (before setting the HtmlBody value, and before creating the TemplateEngine wth this MailMessage).
But it seems it’s not possible to handle the problem with the subject in the same way.
Thank you

Hi,
Thank you for being patient towards the resolution of this issue.
We have further investigated this issue and, hopefully, we will provide a fix for this in the upcoming release of Aspose.Email for .NET. In the meanwhile, you can use the following work around to manage your needs. We appreciate your patience in this regard.
