Maybe, but all other Clients like Thunderbird, KMail and Evolution have absolutely no problem with it ???
TBird, KMail, Outlook-IMAP and Outlook-ActiveSync are mail clients operating on RFC822/2822/5322 data. WebApp (WA) and Outlook-zarafa6client (OL/Z6) are operating on MAPI data however.
Most Internet email traffic is RFCx22-style, so there is a conversion step when feeding mail into a MAPI system such as KC, or MS Exchange. Because MAPI’s uncanny design does not allow for unknown character sets of bodytext, you have two options:
pretend that “unknown-8bit” means “cp1252”. Or “iso-8859-1”. Or “koi8-r”. Since it is impossible to tell, someone will get gibberish at some point, and it will not be recoverable. store raw bytes and leave the interpretation to a 3rd-party software. This involves saving raw data as a (MAPI) attachment, or a RFCx22 data stream (or both).TBird gets passed the RFCx22 data stream, which it then has to parse - and somehow make sense of “unknown-8bit”. It usually just pretends it is ASCII or something, and the user can switch charsets manually until the result makes sense to him.
WA and OLZ6 are MAPI clients and receive the MAPI attachment. Since it is an attachment to them, they don’t do any further parsing by default. IIRC, opening the attachment in Outlook gives you a new sub-window. That should also default to ASCII or something, and the user can again switch charsets manually until the result makes sense to him.
