Exchange Server Active Sync - character encoding issues
To give an example: In the "list of e-mails" view, "äöü" in the mail body looks like "äöü" in the small preview. As soon as I enter the mail, the mail body looks like "äöü".
It's not a problem with the mails themselves: I've tried it with utf-8 encoded mails as well as with iso-8859-1 mails: Both look fine in Outlook, in IMAP clients (Thunderbird, Alpine, ...) and in Outlook Web Access. It's just the iPhone mail application that displays the non-ASCII characters incorrectly, and it only does that when looking at the full mail, not in the preview.
(Technical: On byte level, "ä"(UTF-8) = "ä"(ISO-8859-1) = C3 A4. So to me, it looks like the iPhone gets a correct UTF-8 stream from Exchange (independent of the encoding of the original mail) and then -- for some strange reason -- interprets this UTF-8 stream as ISO-8859-1.)
