The Filename of the attached report file for a report over a period (weekly, monthly, etc) contains a invalid character (en dash / u+2013), which causes some mail clients aren't able to open the mail / attachment.

The filename must built following the rules of the RFC 5987 to allow characters which aren't in ASCII or ISO-8859-1.

Be aware that the filename is identical to the subject of the mail plus the file extension. I did a quick fix changing all en dashes in ./plugins/Intl/lang/de.json (for my use only in german) into dash inside of ASCII code table.

Do you mean the attachments in sent emails via a scheduled report contain invalid characters?

@bwagenseil commented on January 20th 2016

No, the attachments themselves are fine. I mean the filename of the attachment in the header of the mime body. See following part of source code of a email:

--=_7d9a4ed223249f0d3dfea17c59cb11cc
Content-Type: application/pdf
Content-Transfer-Encoding: base64
Content-Disposition: inline; filename="Bericht XXXX - Woche 4.–10. Januar 2016.pdf"
